FLEXIBLE FUEL CELL AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed herein is a flexible fuel cell, including: (i) an anode comprising an anode end plate structure made of a polymer material and provided with a hydrogen flow channel and a collector made of a metal layer deposited on the anode end plate structure; (ii) a cathode comprising a cathode end plate structure made of a polymer material and provided with an air flow channel having air holes and a collector formed of a metal layer deposited on the cathode end plate structure; and (iii) a membrane electrode assembly (MEA) comprising a polymer electrolyte membrane whose surface is coated with a catalyst layer and a gas diffusion layer (GDL) provided on at least one side thereof, wherein the membrane electrode assembly is interposed and pressed between the anode and the cathode.

1. A method of manufacturing a flexible fuel cell, comprising the steps of:
(a) coating a stainless steel substrate serving as a mold with a polymer material and then detaching the substrate from the polymer material using a lift-off process to form an anode end plate structure and a cathode end plate structure; (b) sequentially depositing a first metal layer and a second metal layer on each of the anode end plate structure and the cathode end plate structure using sputtering, thermal evaporation, chemical vapor deposition or electroless plating; and (c) interposing a membrane electrode assembly between the anode end plate structure and the cathode end plate structure and pressing them.
