Fuel cell stack arrangement and a method for treatment of cathode intake air

Abstract

The present invention relates to a fuel cell stack arrangement (1) comprising a fuel cell stack (3) comprising a plurality of fuel cells (3′). Each fuel cell (3′) comprises an anode side (4) comprising a fuel inlet (5) and a fuel outlet (6), a cathode side (7) comprising an air inlet (8) and an air outlet (9), and an electrolyte (24) arranged between the anode side (4) and the cathode side (7). The fuel cell stack arrangement (1) further comprises a cathode air intake (10) arranged upstream from the air inlet (8), a cathode air compressor (11) arranged downstream from the cathode air intake (10) and a hydrogen gas storage tank (12) arranged upstream from the fuel inlet (5). The fuel cell stack arrangement (1) further comprises a first separating unit (13) comprising at least one disc stack separator (14) and being arranged between the cathode air intake (10) and the air inlet (8).
