VERFAHREN ZUM REINIGEN MINDESTENS EINES EINTRITTSKANALS FÜR BETRIEBSGAS EINER BRENNSTOFFZELLE EINER BRENNSTOFFZELLENANORDNUNG UND BRENNSTOFFZELLENANORDNUNG

摘要

The invention relates to a method for cleaning at least one inlet channel of a fuel cell of a fuel cell arrangement (2), wherein operating gas (10) and electric current are conducted through fuel cells (4) which are electrically connected in series. The cleaning can be achieved simply by blowing out contaminants from an inlet channel of a fuel cell (4) laid therewith if the operating gas supply is interrupted while the electric current is maintained and gas builds in the fuel cell (4).
