VERFAHREN ZUM BETRIEB VON BRENNSTOFFZELLEN

摘要

In high-temperature fuel cells, for example the solid oxide fuel cell (SOFC) and molten carbonate fuel cell (MCFC), anode waste gases containing hydrogen and carbon dioxide are separated from the waste gas stream by means of, e.g., a scrubbing step and/or an adsorption system, and the thus-obtained hydrogen is recycled to the anode. For the operation of an MCFC system, the carbon dioxide separated from the anode waste gas is reused by being admixed to the oxygen stream entering the cathode.
