A fuel cell stack and reformer assembly is provided, for use in fuel cell stack system assemblies requiring a reformer to fully or partially reform inlet fuel, comprising a base plate 11; a fuel cell stack 19; a reformer unit 1 which comprises a reformer 2, a fuel steam mix inlet 14, a reformate chamber 30, and a reformate outlet 18a, wherein a wall of the reformate chamber 30 defines a heat exchange interface 17; and a fuel steam mixing chamber 10 having inlets for fuel and steam and an outlet arranged to feed into the fuel steam mix inlet 14 of the reformer. The fuel steam mixing chamber 10 is disposed between the base plate 11 and the reformate chamber 30 so as to act as a thermal break, and is in part defined by the heat exchange interface 17 so as to enable heat exchange between in-use reformate gas 15 in the reformate chamber and in-use fuel steam mix 9 in the fuel steam mixing chamber 10, in order to cool the reformate gas 15 to a temperature at or below the operating temperature of the fuel cell stack 19. |
