A modular unitized electrochemical fuel cell cartridge (20) is formed from a mono-polar anode plate (22), a second mono-polar cathode plate (24 ) and a solid polymer membrane electrode assembly (26) operably interposed between the anode and the cathode. An electrochemical fuel cell stack is provided having at least one removable fuel cell cartridge, a pair of current collectors which are individually disposed on opposite sides of the anode and the cathode plates and a pair of end plates which are individually disposed on opposite sides of the current collectors from the anode and cathode plates. Sealing ridges (42) and mating grooves (44) as well as alignment means (46) enable the easy assembly of a modular unitized fuel cell cartridge and stacking said cartridge.
