Fuel cell exhibiting enhanced hydrogen distribution density

摘要

This invention provides a fuel battery comprising a solid polymer electrolyte membrane, an anode-side catalyst body and a cathode-side catalyst body disposed respectively on both sides of the solid polymer electrolyte membrane, and a fuel guide part in which the anode-side catalyst body is disposed opposite to the anode-side catalyst body on the opposite side where the anode-side catalyst body faces the solid polymer electrolyte membrane and which guides a fuel which has been externally supplied toward the center of the face of the anode-side catalyst body.
