Abstract
A membrane electrode assembly is provided that includes a nanostructured thin film catalyst as the anode electrode catalyst, the membrane electrode assembly having robustness to humidity variation. Additionally, a solid polymer fuel cell including this membrane electrode assembly is provided. A membrane electrode assembly of an embodiment of the present disclosure includes an electrolyte membrane; an anode electrode catalyst layer in contact with the electrolyte membrane; an anode gas diffusion layer; and a fluorinated polymer layer in contact with the anode electrode catalyst layer between the anode electrode catalyst layer and the anode gas diffusion layer. The anode electrode catalyst layer includes a plurality of nanostructure elements including acicular microstructured support whiskers supporting nanoscopic catalyst particles; and the fluorinated polymer layer includes one of fully-fluorinated or partially-fluorinated polymer particles that have been dispersed in a network form.
