Title:
FUEL CELL AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/044415
Kind Code:
A1
Abstract:
Provided is a fuel cell which can stop the supply of fuel and/or air during abnormal heating, thereby suppressing any further abnormal heat generation. A fusible porous film (21A) is provided between a cathode (11) of an electrode structure (10) (power generation unit) and an external cover member (15) on the cathode side, and a fusible porous film (21B) is provided between an anode (13) and an external cover member (16) on the anode side. The fusible porous films (21A, 21B) may be constructed from a low melting-point resin which is insoluble in the fuel (methanol), or may be constructed by combining a porous film and a low melting-point polyolefin wax. When abnormal heat is generated in a fuel cell (1), the fusible porous films (21A, 21B) are thermally fused, pores are eliminated, and the supply of fuel and/or air is reliably cut off.
