Both of these membrane products are belonging to the unreinforced category, i.e., there is no mechanical reinforcement in them.  Unreinforced PEM is also known as self-supporting material in the market. These membrane products are manufactured via extrusion melt process. Both of these membranes are manufactured from the chemically stabilized PFSA resin to achieve longevity for the demanding applications. The polymer structure for both of these products are based on the long-side-chain PFSA for its chemical composition. Unreinforced proton exchange membranes based on the long-side-chain PFSA will usually exhibit high proton or ionic conductivity as a result of their affinity to interact with water molecules and keep these within the membrane itself.  This affinity towards water molecules also induces swelling in the membrane.\u003c\/p\u003e\n\u003cp\u003eBoth of these proton exchange membranes (i.e., 175 and 120 micrometers thick) are usually considered to be relatively thick membranes compared to what are available in the market and suitable for pressurized applications such as high pressure PEM electrolyzers or applications that demand membranes with low crossover properties such as alcohol and organic fuel consuming fuel cells.  When safety and longevity are the critical determinants in a product development, use of this membrane product is recommended. Examples of other applications that can benefit from this membrane are given below. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable height=\"181\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"564\" style=\"border-collapse: collapse;

Membrane thickness for D80R-Pt is approximately 80 micrometers (~3.1 mil). D50R-Pt membrane has a thickness of ~50 microns (~2 mil). Both of these membrane products belong to the reinforced category, i.e., there is a mechanical reinforcement web in them. The reinforcement is based on the ePTFE (also known as expanded PTFE) and provides excellent mechanical robustness.  Gas recombination catalyst layer (which is an integral part of the membrane) is composed of Pt based nanoparticles and will recombine the crossing over gas species (H2 and O2 molecules) and generate water molecules as a result of the recombination reaction. Previous research demonstrates that making the gas recombination an integral part of the membrane is the most promising way to modify these proton exchange membranes in a way to reduce the gas crossover issues. Presence of ePTFE mechanical reinforcement, Pt-based gas recombination catalyst layer, and manufacturing the final membrane product in a thickness of ~80 microns truly brings the best of the all components and makes this membrane product an ideal proton exchange membrane for pressurized and unpressurized PEM electrolyzer stacks.  D50R-Pt, on the other hand is an ideal proton exchange membrane for atmospheric and pressurized proton exchange membrane fuel cells (PEMFC) stacks. While it is not common to use 80 micrometers thick membranes for PEMFC stacks, certain applications such as regenerative fuel cells operating at high pressures can benefit from 80 micrometers thick membrane.  PEM electrolysis applications has been mainly using PFSA membranes thicker than 50 micrometers for safety and longevity reasons, though atmospheric PEM electrolyzers can greatly benefit from D50R-Pt membrane when superior electrochemical performance is required.\u003c\/p\u003e\n\u003cp\u003eBoth D80R-Pt and D50R-Pt membranes are manufactured via solution casting process. Chemically stabilized PFSA resin is used in the production of these membranes to achieve longevity for the demanding applications. The polymer structure of these membranes are based on the long-side-chain PFSA for its chemical composition. Proton exchange membranes based on the long-side-chain PFSA will usually exhibit superb proton or ionic conductivity as a result of their affinity to interact with water molecules and keep these within the membrane itself.  This affinity towards water molecules also induces swelling in the membrane. The presence of ePTFE reinforcement reduces the degree of swelling greatly (for the length and width aspects) for these membranes compared to the unreinforced membrane products.\u003c\/p\u003e\n\u003cp\u003eD80R-Pt membrane is usually considered to be intermediate thickness compared to other reinforced membranes available in the market. When mechanical robustness, low gas crossover, and longevity are the critical determinants in a product development, use of this membrane product is recommended. D50R-Pt, on the other hand, can be considered as a thin to intermediate thickness for its application range compared to other reinforced membranes available in the market.  Demanding PEMFC applications such as pressurized H2\/Air and H2\/O2 reactants consuming fuel cell stacks will greatly benefit from the use of D50R-Pt membrane. Examples of applications that can benefit from these membranes are given below. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable height=\"183\" style=\"border-collapse: collapse;

D50R membrane has a thickness of ~50 microns (~2 mil). Both of these membrane products belong to the reinforced category, i.e., there is a mechanical reinforcement web in them. The reinforcement is based on the ePTFE (also known as expanded PTFE) and provides excellent mechanical robustness.  Presence of ePTFE mechanical reinforcement and manufacturing the final membrane product in a thickness of ~80 microns brings the best of the all components and makes this membrane product an ideal proton exchange membrane for pressurized and unpressurized PEM electrolyzer stacks.  D50R membrane, on the other hand, is an ideal proton exchange membrane for atmospheric and pressurized proton exchange membrane fuel cells (PEMFC) stacks. While it is not common to use 80 micrometers thick membranes for PEMFC stacks, certain applications such as regenerative fuel cells operating at high pressures can benefit from 80 micrometers thick membrane.  PEM electrolysis applications has been mainly using PFSA membranes thicker than 50 micrometers for safety and longevity reasons, though atmospheric PEM electrolyzers can greatly benefit from D50R membrane when superior electrochemical performance is favored.  \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eBoth D80R and D50R membranes are manufactured via solution casting process. Chemically stabilized PFSA resin is used in the production of these membranes to achieve longevity for the demanding applications. The polymer structure of these membranes are based on the long-side-chain PFSA for its chemical composition. Proton exchange membranes based on the long-side-chain PFSA will usually exhibit superb proton or ionic conductivity as a result of their affinity to interact with water molecules and keep these within the membrane itself.  This affinity towards water molecules also induces swelling in the membrane. The presence of ePTFE reinforcement reduces the degree of swelling greatly (for the length and width aspects) for these membranes compared to the unreinforced membrane products.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eD80R membrane is usually considered to be intermediate thickness compared to other reinforced membranes available in the market. When mechanical robustness and longevity are the critical determinants in a product development, use of this membrane product is recommended (especially for atmospheric or pressurized PEM electrolyzers). D50R, on the other hand, can be considered as a thin to intermediate thickness for its application range compared to other reinforced membranes available in the market.  Demanding PEMFC applications such as pressurized H2\/Air and H2\/O2 reactants consuming fuel cell stacks will greatly benefit from the use of D50R membrane.
