METHOD AND SYSTEM FOR THERMAL MANAGEMENT OF A FUEL CELL

摘要

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.
