Abstract
A low-temperature fuel cell assembly including of a low-temperature fuel cell () in combination with a sweeping gas circuit () for at least the anode part thereof. The fuel gas is prepared by filtering via a semi-permeable wall () and the yield from this process is increased by employing sweeping gas. This sweeping gas is obtained by producing it in the sweeping gas circuit (). During operation some of the sweeping gas is continuously discharged and fresh sweeping gas is continuously produced. With this arrangement it is possible to use hydrogen as fuel gas. Sweeping gas is obtained by injecting air () and combusting () the oxygen contained therein with hydrogen. It is also possible to perform a methanisation reaction starting from hydrogen as fuel gas by providing CO/COas a result of which the sweeping gas is methane.
