A manifold seal for a fuel cell system includes a sealing area defined by a peripheral portion of a fuel cell stack of the fuel cell system and a portion of an end plate positioned on the fuel cell stack. The manifold seal includes a manifold frame defining a mating surface which sealingly engages the sealing area. The mating surface has a slot formed therein which opens towards the sealing area. The manifold seal includes a bracket defining a base portion and having a lip projecting from an edge thereof. The base portion is moveably secured to a face of the end plate so that the edge is positioned on the sealing area. The base portion is positioned inwardly from the sealing area and the manifold frame. The lip is moveably engaged in and cooperates with the slot to seal a gap between the mating surface and the sealing area.

A method of using a catalyst body able to support gas flow therethrough and having a catalyst for promoting a catalytic reaction of a component of a first gas and being able to be regenerated by a second gas, comprising: providing at least the first gas and the second gas; and repeatedly moving successive parts of the catalyst body into communication with the first gas and then into communication with the second gas; wherein: the part of the catalyst body in communication with the first gas causes the component of the first gas to be reacted as the first gas passes though and exits the part of the catalyst body; and the part of the catalyst body in communication with the second gas has the catalyst of that part regenerated as the second gas passes through and exits the part.
