FeNi cathalyst for polymer electrolyte fuel cells

Polymer electrolyte fuel cell (PEMFC) with FeNi cathode electrocatalyst is studied as an alternative to commonly used platinum and/or its alloys. A simple geometry with Pt particles deposited on carbon paper by ink spraying and thermal evaporated FeNi alloy on carbon paper are pressed on flurorosulfonated membrane in a membrane electrode assembly and tested in PEMFC hydrogen-air. Open circuit potential function of hydrogen-air pressure measured at 60 degrees C- set point and 90% relative humidity reached 510 mV for 200KPa hydrogen and air pressure.
