FUEL CELL SYSTEM AND METHOD OF OPERATING SUCH FUEL CELL SYSTEM

摘要

The fuel cell system (1) comprises a fuel cell stack (9), a methanol reformer (6) and an evaporator (4). The fuel cell stack (9) is composed by a number of PEM fuel cells and having an anode inlet (8), an anode outlet (10), a cathode inlet (13) for ambient air, and a cathode outlet (16). The PEM fuel cells have an operating temperature of at least 120º C. The methanol reformer (6) is a single-step steam reformer that is directly coupled to the anode inlet (8) of the fuel cell stack (9) without any intermediate CO cleanup system. Furthermore, a method of operating a fuel cell system (1) is disclosed.
