PROCESS TO CONTROL PRESSURE IN THE ANODE OF A FUEL CELL AND FUEL CELL

摘要

The method involves feeding hydrogen (2) to the anode and air or oxygen (3) to a cathode (5) by a pressure feeding unit (33). A pressure output unit (34) is opened for the periodic removal of a mixture (28) to feed the hydrogen and to send the mixture over an outlet conduit (29) to a reservoir (30). The pressure in the reservoir matches the pressure of the hydrogen being fed, after which the pressure output unit is closed. A pressure feedback control unit (37) and the pressure feeding unit are regulated in a way that the pressure in the anode is matched to a fixed set point (40).
