LIQUID FUEL SUPPLY BOARD, PASSIVE DRIVE TYPE FUEL CELL, AND LIQUID FUEL SUPPLYING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a passive type fuel cell of smaller size which does not use auxiliary units such as a blower and a pump for a making liquid fuel flow in a flow path.

SOLUTION: The objective is evenly supplying fuel to MEA. There are provided a porous body and a liquid fuel supply board which evenly supplies liquid fuel in the porous body surface. The length of all conduits connecting a liquid fuel supply source with a through hole is uniform, and such liquid fuel supply board as the width and depth of the conduit is uniform is used. As a liquid feeding method from the liquid fuel supply source, such method as relies on capillary force which the conduit has is used.
