MEMBRANE ELECTRODE ASSEMBLY, PRODUCTION METHOD FOR SAME, AND FUEL CELL

摘要

Disclosed is a membrane electrode assembly which is capable of further improving the power generation performance of a fuel cell. Ribs (22) separating adjacent gas channels (21) are less porous than the region (23) below the ribs, thus suppressing the deformation of the ribs, suppressing the excessive transmission of reactant gas and enabling the further improvement of power generation performance.
