A method of producing a flow field plate for a fuel cell comprises over-profiling relief features in a die set to more accurately reproduce the intended flow channel features in the pressed plate. The process includes determining a target relief profile of features extending across the plate along at least a first dimension of the plate, modulating the relief profile with an over-profiling parameter, as a function of the first dimension; forming a die with the modulated relief profile; and pressing a flow field plate using the die with modulated relief profile to thereby produce the unmodulated, target relief profile in the flow field plate.

A gas filling apparatus for filling a plurality of gas storage vessels with a gas, the apparatus comprising a plurality of gas filling ports, each port configured to introduce gas into one of the gas storage vessels, and a controller configured to supply gas to the gas filling ports for filling the vessels and to control the supply of gas to all of the gas filling ports based on a property of any one of the vessels.

Gas filling apparatus and method

A separator plate in an air-cooled fuel cell comprises a series of airflow channels, each channel extending longitudinally between first and second opposing edges of the separator plate. Each channel has a cross-sectional profile defining an airflow cross-section at points along the length of the channel, and at least selected ones of the channels each have a thermally conductive structure extending into the channel cross-section at selected intermediate longitudinal positions of the channel. The positions are disposed over an active area of the fuel cell, to locally enhance heat transfer from the active area via the plate to airflow moving through the channel.
