Abstract: The present disclosure provides a fuel cell comprising at least one fuel cell board (200), (400). Each fuel cell board (200), (400) comprises a Membrane Electrode Assembly (MEA) (113) comprising at least one ion permeable membrane, at least one anode, and at least one cathode, wherein each or all anodes are arranged on a first surface of the ion permeable membrane and each or all cathodes are arranged on a second surface of the ion permeable membrane. Each fuel cell board (200), (400) also comprises a first printed circuit board (PCB) layer (101), (401) comprising at least one first fluid path. Each fuel cell board also comprises a second PCB layer comprising (102), (402) at least one second fluid path.

Abstract: The present disclosure provides a fuel cell comprising: at least one fuel cell board, the or each fuel cell board comprising at least one ion permeable membrane, at least one anode and at least one cathode, the at least one anode and the at least one cathode arranged on opposite surfaces of the at least one ion permeable membrane; and at least one first fluid path arranged to supply a coolant fluid to the at least one fuel cell board, wherein the first fluid path is arranged adjacent the at least one anode such that the coolant fluid is substantially directed only to the at least one anode of the at least one fuel cell board.
