ELASTIC MEMBER FOR METHANOL FUEL CELL CARTRIDGE

摘要

This invention provides an elastic member for a methanol fuel cell cartridge, comprising an elastomer having a compression permanent set of 1 to 80 and a hardness (type A) of 40 to 70 and having an operating limit time of not less than 10,000 hr as determined by a DMFC performance test for the fuel cell. The elastic member can prevent leakage of methanol from a methanol fuel cell cartridge, or a connection part between the cartridge and a fuel cell body and, at the same time, can realize long-term operation of the fuel cell without causing a deterioration of power generation performance.
