  • Flow field plates and a method for forming a seal between them
    Publication number: 20040151972
    Abstract: A flow field plate having a plurality of protrusions formed integrally on at least on surface, said protrusions being adapted in use to join the flow field plate to an adjacent flow field plate. The material of the plate may be an electrically conductive polymer, which may comprise a conductive filler and carbon nanofibres. The plates may be welded together by ultrasonic welding.

  • Fuel cell or electrolyser construction
    Publication number: 20040142225
    Abstract: A fuel cell or electrolyser stack comprises countercurrent radially directed fuel and oxidant flow fields on either side of a membrane electrode assembly. A first reactant may flow radially outwardly from a manifold to a first reactant drain and a second reactant may flow inwardly from the edge of the assembly to a second reactant drain.
