PROBLEM TO BE SOLVED: To reduce pressure loss of the reaction gas of a temperature moisture exchanging part in a fuel cell system moisturing the unreacted gas through a temperature moisture exchanging film using reacted gas of a fuel cell. SOLUTION: With a solid polymer film 6 as an electrolyte, a solid polymer fuel cell system is equipped with a solid polymer fuel cell stack 1 equipped with a reactive part consisting of a fuel electrode and an oxidizer electrode for reacting the gas, reacted gas passed through the reacting part of the fuel cell stack 1, and a temperature moisture exchanging means 20 which is equipped with a passage forming a given gas passage against the surface of a temperature moisture exchanging film 24 to exchange heat and moisture with unreacted gas before passing the reacting part of the fuel cell stack 1. The passage is made of a thin plate which is able to be pass formed, with a plurality of braces 26 formed on at least one side of its surfaces. |
