Document Type and Number:
Japanese Patent JP7095549
Kind Code:
B2
Abstract:
A fuel cell separator capable of surely discharging produced water, and a method and apparatus for producing the same. The fuel cell separator is formed in a wave shape with recesses and projections alternately arranged in a first direction, the recesses forming reactant gas channels together with a membrane electrode assembly and the projections abutting the membrane electrode assembly, in which on a surface of the fuel cell separator that is adapted to face the membrane electrode assembly, a plurality of first grooves extending in the first direction along the corrugation of the recesses and projections is disposed at intervals from each other in a second direction orthogonal to the first direction, and a second groove extending in the second direction and communicating with the plurality of first grooves is disposed in the bottom portion of each recess.
