Title:
FUEL CELL AND ELECTROLYTE IMPREGNATION TREATMENT METHOD
Document Type and Number:
Japanese Patent JPH0620714
Kind Code:
A
Abstract:

PURPOSE: To effectively remove the residual organic solvent and binder inside an electrolytic substrate at initial temperature rise of a fuel cell.

CONSTITUTION: Branch pipes 22 and 23 are provided in the middles of exhaust pipes 18 and 19 for anode gas 12 and cathode gas 13 of a fuel battery, and gas suction mechanisms 26 and 27 for sucking and exhausting gas are provided through valves. Furthermore, a branch pipe 36 is also provided in the middle of a purge gas exhaust pipe 30, a gas suction mechanism 38 for sucking and exhausting gas is added through a valve 37 so as to increase the influence. So, since it is so arranged as to suck and remove the gas inside the exhaust pipe through exhaust pipes, the residual organic solvent generated from an electrolytic substrate and a binder can be removed. As a result, the deterioration of electrolyte accompanying the abnormal heating by an organic solvent or the drop of the battery capacity by the inequality in impregnation can be prevented.
