Abstract (en)
[origin: WO2019137924A1] The invention relates to a fuel cell arrangement (10) having an anode (26) connected to an H2 inflow (48) and a cathode (30) connected to an O2 inflow (50), wherein a differential pressure control device (52) is arranged between the H2 inflow (48) and the O2 inflow (50) for controlling the differential pressure between the H2 inflow (48) and the O2 inflow (50), the differential pressure control device (52) having a fluid connection (54) between the H2 inflow (48) and the O2 inflow (50) in which a deflectable diaphragm is arranged, to which a pin (64) is coupled which, when the diaphragm (56) is deflected, opens a valve (58) arranged in the H2 inflow (48) as a result of positive O2 pressure.
