Reforming chamber for fuel cell system, and full cell system

The invention discloses a reforming chamber for a fuel cell system, and a fuel cell system. The reforming chamber comprises an aluminum-magnesium alloy flow field plate and a sealed end plate; the aluminum-magnesium alloy flow field plate comprises a flow field, a composite catalyst and a composite carrier; the composite carrier is formed on the surface of the flow field; the composite carrier iscomposed of aluminum oxide and magnesium oxide; the composite catalyst is formed on the composite carrier; the composite catalyst is composed of elemental copper, copper oxide, germanium dioxide and indium sesquioxide; the composite carrier is formed through electrochemical corrosion method, and the composite catalyst is formed through reaction plasma spray-coating method and cold spray-plating method. The reforming chamber disclosed by the invention has high methanol conversion rate and low CO selectivity, and further has good capacity of resisting sulfide poisoning. 本发明公开了种燃料电池系统用重整室及燃料电池系统，重整室包括铝镁合金流场板和密封端板，铝镁合金流场板
