Document Type and Number:
Japanese Patent JP7302532
Kind Code:
B2
Abstract:
A fuel cell capable of reducing the stress exerted upon an electrolyte membrane resulting from the swelling and contraction of the electrolyte membrane. The fuel cell includes at least an MEGA with catalyst layers joined to the opposite sides of the electrolyte membrane, and a pair of separators disposed so as to sandwich the MEGA. The MEGA generates power with a hydrogen gas fed to one side of the MEGA and with an oxidant gas fed to the other side. Separators each have a plurality of projections formed on the side of the MEGA so as to form a gas channel through which the hydrogen gas or oxidant gas flows between the projections. The electrolyte membrane has a plurality of through-holes formed at positions facing the projections along the direction in which the projections extend.
