Abstract
An active material layers for a fuel cell membrane electrode assembly includes metal oxide particles, a non-ionomer proton conductor and active catalyst particles supported on the metal oxide particles.
Claims5
A fuel cell membrane electrode assembly comprising:
- a membrane;
- an active material layer formed on opposite sides of the membrane;
- a gas diffusion layer for diffusing hydrogen on one active material layer;
- a hydrogen source for delivering the hydrogen to the gas diffusion layer;
- another gas diffusion layer for diffusing oxidant on another active material layer;
- and
- an oxygen source for delivering the oxidant to the other gas diffusion layer, wherein each active material layer comprises composite particles consisting of:
- non-carbon metal oxide support particles;
- hydrous ruthenium dioxide as a non-ionomer proton conductor;
- active catalyst particles supported on the non-carbon metal oxide support particles;
- and
- a binder, wherein the active material layer comprises no ionomer proton conductor.
