MPL section is made from sintered Ti particles in a more dense form and a much better surface roughness in order to establish good electrical contact and porosity gradient from the MPL side to the back felt side, similar to carbon based gas diffusion layers with MPL used in the PEM fuel cells.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: justify; text-justify: inter-ideograph;\" class=\"MsoNormal\"\u003e\u003cspan\u003eThe following SEM images show both Ti fiber felt side and MPL side of this product that clearly demonstrates the difference in surface roughness and thus contact area and resistance. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: justify; text-justify: inter-ideograph;\" class=\"MsoNormal\"\u003e\u003cspan\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0600\/9022\/0677\/files\/Ti_felt_with_MPL.jpg?v=1778258874\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: justify; text-justify: inter-ideograph;\" class=\"MsoNormal\"\u003e\u003cspan\u003eWhile titanium based fiber felts (with or without MPL) are predominantly used in PEM electrolyzers as the metallic diffusion layers, anion exchange membrane water electrolyzers (AEMWE) can greatly benefit from the use of titanium based metallic diffusion layers since the concentration of the alkaline electrolytes (such as NaOH or KOH) in AEMWE systems is in the range of 0-1 Molar. With such low concentrations, titanium fiber felt with MPL is expected to work great because of its chemical stability. For further stability and corrosion protection, this product can also be platinized using the methods available in the literature to further improve the longevity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: justify; text-justify: inter-ideograph;\" class=\"MsoNormal\"\u003e\u003cspan\u003ePEM electrolyzer cells with solid acid membranes such as Nafion, Aquivion, and any other perfluorosulfonic acid (PFSA) membranes and alkaline electrolyzers with anion exchange membranes can utilize titanium fiber felt with MPL as the anode and cathode diffusion layer. Furthermore, the pristine titanium fiber felt with MPL can also be catalyst coated with the appropriate anode and cathode catalyst in order to be used as the anode and\/or cathode electrodes. This catalyst coating can also be implemented on the platinized Titanium fiber felt with MPL in order to improve the longevity aspect for highly demanding applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: justify;
