In this work, a membrane electrode assembly (MEA) for proton exchange membrane fuel cell (PEMFC) operating under no external humidification has been successfully fabricated by using a composite Pt/SiO 2 /C catalyst at the anode. In the composite catalyst, amorphous silica, which originated from the
## TRENDS environments was investigated. The corrosion rate is higher under 'outlet' conditions at 700ยฐC compared to standard conditions at 650ยฐC and 'inlet' conditions at 600ยฐC. The corrosion potential increases with time when a protective corrosion layer is formed. Eventually it reaches a more po
predicted assuming isothermal conditions. It was also found that Knudsen diffusion has to be taken into account in modeling gas transport.
