STRUCTURE OF A POWER GENERATION CELL FOR A FUEL CELL AND WETTING METHOD FOR POWER GENERATION CELL

摘要

PROBLEM TO BE SOLVED: To provide a structure of a power generation cell for a fuel cell which does not deteriorate power generating voltage by preventing liquid from pooling in a porous member which is a gas flowing section.

SOLUTION: The structure of the power generation cell for the fuel cell is provided with: a gas flowing path body 14 placed in a membrane electrode assembly 11 and formed by a porous body through which the gas can flow through: and a porous liquid movement sheet 15 abutted to the gas flowing path body 14 on at least an upstream side and a downstream side in the direction of the gas flow with lower porosity and higher hydrophylic property than the gas flowing path body 14. The liquid which is generated by catalyst reaction of the gas flowing through the gas flowing path body and absorbed by the liquid movement sheet 15 in a downstream side abutting part by flowing downstream is moved from the upstream side abutting part to the gas flowing path body 14 and wets the gas flowing through the upstream side of the gas flowing path body 14.
