FUEL CELL, FUNCTION CARD, GAS SUPPLY MECHANISM FOR FUEL CELL, POWER GENERATOR AND PRODUCTION METHOD FOR POWER GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell having a structure of ensuring a reliable gas supply even in a limited space without impairment of portability.

SOLUTION: The fuel cell of the present invention comprises a proton conductor membrane, flat hydrogen-side electrode and oxygen-side electrode that sandwich the proton conductor membrane, means 13 for supplying fuel to the hydrogen-side electrode, and flat collectors 16 and 17 in close contact with the oxygen-side electrode and formed with a permeating part such as opening that exposes the oxygen-side electrode to the atmosphere. The oxygen-side electrode exposed to the atmosphere allows oxygen to be supplied to power generators 11 and 12 without lowering an oxygen partial pressure in the air.
