BY-PRODUCT GAS ABSORBENT FOR HYDROCARBON FUEL CELL, FILTER CONTAINING THE ABSORBER, AND BY-PRODUCT GAS ABSORBING SYSTEM IN WHICH THE BY-PRODUCT GAS ABSORBER OR THE FILTER IS INCORPORATED

摘要

PPROBLEM TO BE SOLVED: To provide a by-product gas absorber for effectively removing harmful substances such as aldehyde and formic acid generated as reactive by-products and a hydrocarbon fuel cell in which the by-product gas absorber is used. PSOLUTION: An aldehyde gas absorber formed of aminoguanidine salt and/or hydrazide compound and an organic acid gas deodorizer are installed in the harmful gas absorbing part of the hydrocarbon fuel cell. Consequently, formaldehyde, etc., generated as reactive by-products can be effectively absorbed. PCOPYRIGHT: (C)2008,JPO&INPIT
