SOLID POLYMER FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce pressure loss of reaction gas in a fuel cell system humidifying un-reacted gas via a water retaining porous body by using reacted gas of a fuel cell. SOLUTION: The pressure loss of the reactive gas can be reduced by providing a solid polymer fuel cell stack 1 with a plurality of laminated single cells using solid polymer films 6 as electrolytes and a humidity and temperature exchanging means with a plurality of humidity and temperature exchanging cells exchanging heat and moisture of the reacted gas having passed a reaction part of the fuel cell stack 1 and the un-reacted gas before passing the reaction part of the fuel cell stack 1 laminated perpendicularly to a laminating direction of the single cells, and integrating reactive gas collecting and distributing manifolds for the humidity and temperature exchanging means and reactive gas collecting and distributing manifolds for the fuel cell stack.
