A fuel cell manifold arrangement (5) includes a fuel cell stack (103) and a manifold enclosure (10) connected to and sealed to an inlet side of the fuel cell stack (103) and defining with the stack a gas plenum (21) for receiving a fuel gas (14) for the fuel cell stack (103). A catalyst screen (15) is connected to the manifold enclosure (10) for defining a gas passage for passing fuel gas (14) and for containing a catalyst (13) that is bounded by the screen (15). The manifold enclosure (10) has a gas inlet for receiving fuel gas (14), the gas inlet communicating with the screen (15) for passing fuel gas (14) through the screen (15) and past the catalyst (13). A plate (12) in the manifold enclosure (10) separates the catalyst (13) from the plenum (21), and heat insulation (23) is provided on at least part of the manifold enclosure (10) and on at least part of the plate (12) for insulating the manifold enclosure (10) from the fuel cell stack (103) and from an exterior of the manifold enclosure (10). A passage (24) in the manifold enclosure (10) connects the screen (15) to the plenum (21) for passing fuel gas (14) from the catalyst (13) to the plenum (21). |
