PROCESS AND DEVICE TO REMOVE INERT IMPURITIES Russian patent published in 2002 - IPC

FIELD: fuel cells with gaseous reagents. SUBSTANCE: device to remove inert impurities from at least one working gas of battery of fuel cells has inlet line with controllable valve to feed working gas into battery of fuel cells and one outlet line with controllable valve to release working gas from battery of fuel cells and at least two fuel cells with working gas connected in series and positioned upstream from outlet line for release of working gas from battery of fuel cells. Salient feature of invention lies in that section of inlet line feeding working gas between valve and battery of fuel cells is linked through controllable valve to proper inlet of at least one fuel cell connected in series and positioned upstream from outlet line releasing working gas from battery of fuel cells. EFFECT: increased efficiency of removal of inert impurities from battery of fuel cells by blasting. 4 cl, 1 dwg
