Fuel battery

摘要

Provided is a fuel battery including: a fuel battery cell assembly having at least two fuel battery cells coplanarly disposed, the fuel battery cell including a membrane electrode assembly having an anode, an electrolytic membrane, and a cathode stacked on one another in this order, and a flow channel plate provided on an anode side and having on an anode-side surface thereof an in-cell fuel flow channel through which liquid fuel flows; and a fuel distributor having an out-cell fuel flow channel connected to each of the in-cell fuel flow channels to distribute the liquid fuel to the fuel battery cells.

1. A fuel battery comprising:
a fuel battery cell assembly having at least two fuel battery cells coplanarly disposed, the fuel battery cell including a membrane electrode assembly having an anode, an electrolytic membrane, and a cathode stacked on one another in this order, and a flow channel plate provided on an anode side and having on an anode-side surface thereof an in-cell fuel flow channel through which liquid fuel flows; a fuel distributor having an out-cell fuel flow channel connected to each of the in-cell fuel flow channels to distribute said liquid fuel to the fuel battery cells; wherein the fuel battery cell assembly includes at least two fuel battery cells linearly disposed; wherein the fuel distributor is disposed on a lateral side of the fuel battery cell assembly and along an array direction of the at least two fuel battery cells linearly disposed; and wherein said fuel battery cells further include: a liquid-gas separation layer disposed between said membrane electrode assembly and said flow channel plate and having permeability for a vaporized matter of said liquid fuel; and an intervening layer disposed between said liquid-gas separation layer and said flow channel plate so as to cover said in-cell fuel flow channels and having a contact angle to water of less than 70 degrees.
