Abstract
A fuel cell includes a membrane electrode assembly and a separator. In the membrane electrode assembly, an electrolyte membrane is sandwiched between catalyst layers. The separator includes ribs that are in contact with the membrane electrode assembly and a passage that is provided between the ribs and configured to circulate a gas supplied to the electrolyte membrane. In an in-plane direction of the catalyst layers, an amount of a catalyst metal contained in the catalyst layers is larger in an under-passage region located immediately below the passage than in an under-rib region located immediately below the ribs.
Claims5
A fuel cell comprising:
- a membrane electrode assembly in which an electrolyte membrane is sandwiched between catalyst layers;
- and
- a separator comprising ribs that are in contact with the membrane electrode assembly and a passage that is provided between the ribs and configured to circulate a gas supplied to the electrolyte membrane, wherein
- in an in-plane direction of the catalyst layers, an amount of a catalyst metal contained in the catalyst layers is larger in an under-passage region located immediately below the passage than in an under-rib region located immediately below the ribs.
