A method for the thermal management of a fuel cell, which method comprises: processing a fuel supply stream comprising hydrogen, steam, at least one carbon oxide and optionally methane using a methanator to produce a fuel cell supply stream comprising a controlled concentration of methane; and reforming within the fuel cell methane present in the fuel cell supply stream, wherein the way in which the methanator is operated is adjusted in response to fluctuations in the temperature of the fuel cell such that the concentration of methane in the fuel cell supply stream is controlled in order to achieve a desired level of reforming of methane within the fuel cell.

Thermal management of a fuel cell system

A method of operating a fuel cell () in which a gaseous supply stream () comprising a reactive species is delivered to an electrode () where the reactive species is consumed in an electrochemical reaction to produce an exhaust stream () which is depleted in reactive species, which method comprises: a) assessing the concentration of reactive species in the exhaust stream (); b) relating the concentration of reactive species in the exhaust stream () to a maximum current that may be drawn from the fuel cell () without redox damage of the electrode; and c) adjusting the way in which the fuel cell () is operated in order to optimize efficiency without redox damage of the electrode ().
