Patent ID: 8007952

Claim:
A fuel cell comprising: an electrolyte membrane; a first electrode bonded to one surface of the electrolyte membrane; a second electrode bonded to the other surface of the electrolyte membrane; a first current collector which is provided between the electrolyte membrane and the first electrode and which is in contact with the first electrode such that at least a part of the first current collector is embedded in the electrolyte membrane; and a flat-plate second current collector which is in contact with the second electrode and in which a plurality of fine pores are provided to extend in a direction substantially perpendicular to the planar direction of the second current collector, wherein the first current collector and the electrolyte membrane are chemically bonded, the sides of the first current collector are tapered, and the surface of the first current collector is coated with a conductive material having corrosion resistance, wherein the second current collector is provided between the electrolyte membrane and the second electrode, and the second current collector is in contact with the second electrode such that at least a part of the second current collector is embedded in the electrolyte membrane at a distance from the first current collector, and wherein the flat-plate second current collector and the electrolyte membrane are chemically bonded, the sides of the second current collector are tapered, and the surface of the second current collector is coated with a conductive material having corrosion resistance.
