FUEL CELL SYSTEM AND METHOD FOR STARTING A FUEL CELL SYSTEM

摘要

The invention relates to a method of starting up a fuel cell system comprising a reformer (10) and a fuel cell stack (12), the reformer receiving a supply of fuel (14) and air (16) as the starting materials and the fuel cell stack receiving a supply of reformate (18) generated by the reformer. In accordance with the invention it is provided for that the air ratio characterizing the fuel/air ratio of the starting materials supplied to the reformer (10) is varied as a function of a temperature of the fuel cell stack (12). The invention relates furthermore to a fuel cell system.
