Title:
FUEL CELL PERFORMING GAS SEPARATION FROM COOLING WATER
Document Type and Number:
Japanese Patent JP2015213068
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system capable of separating reaction gas, leaking into cooling water that is circulated and supplied to a fuel cell, from the cooling water.SOLUTION: A fuel cell system includes: a fuel cell including an anode, a cathode 132 and a cooling water channel 40; an oxygen-containing gas supply source 34, a supply pipeline 136, an exhaust pipeline 178, a return pipeline 154 and a circulation pump 156 which circulate and supply oxygen to the cathode 132; cooling water circuits 44, 46 for circulating and supplying cooling water to the cooling water channel 40; and an accumulator 142. The accumulator 142 includes cooling water 150 and a gas containing area 152 above the cooling water 150. The oxygen-containing gas exhaust pipeline 178 communicates with the gas containing area 152. The gas containing area 152 communicates with an oxygen-containing gas return pipeline 154 through a porous plug 155 through which only gas can circulate, and gas accompanying with the cooling water returned to the accumulator 142 is returned to the oxygen-containing gas return pipeline 154 together with exhaust gas from the oxygen-containing gas exhaust pipeline 178.
