INTER-CONNECTOR FOR FUEL CELL, AND COLLECTIVE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a lightweight inter-connector for a fuel cell capable of sufficiently reduce an electric resistance, and having a simple structure.

SOLUTION: This inter-connector is disposed between a first single fuel cell and a second single fuel cell each composed by interposing a polymer electrolyte film between a cathode in contact with an oxygen-containing gas flow such as air and an anode in contact with a fuel gas-containing flow containing a fuel gas such as hydrogen. The inter-connector is used for electrically connecting the cathode of the first single fuel cell to the anode of the second single fuel cell. For the inter-connector 30, via-holes for electrically connecting respective metal layers formed on both surface sides of a resin board with each other penetrate the resin board; a groove-like passage 18 for running the oxygen-containing gas flow is opened on the surface of the metal layer formed on the one surface side of the resin board and contacting the cathode of the first single fuel cell; and a groove-like passage 20 for running the fuel gas-containing flow is opened on the surface of the metal layer formed on the other surface side of the resin board and contacting the anode of the second single fuel cell.
