NOVELTY - A fuel cell stack device (1) comprises: proton exchange membrane (110); anode unit (120) disposed on membrane; and organic liquid hydrogen fuel, flowing through anode unit and reacting with anode unit. The anode unit comprises molybdenum oxide that reacts with the fuel to form hydrogen molybdenum bronze. The anode unit is membrane structure. The anode unit comprises first surface disposed on proton exchange membrane, second surface opposite to first surface, and channels (121) disposed on second surface. The device further comprises first bipolar plate (102) disposed on anode unit.    USE - As fuel cell stack device for manufacturing of membrane electrode assembly (claimed).    ADVANTAGE - The fuel cell stack device is lighter weight, has smaller volume, and exhibits higher efficiency, and has decreased manufacturing cost. The cooling channels and the cooling water are not needed by the fuel cell stack device, and thus the volume and the weight of the fuel cell stack device are decreased.    DETAILED DESCRIPTION - A fuel cell stack device (1) comprises: a proton exchange membrane (110); an anode unit (120) disposed on the proton exchange membrane; and organic liquid hydrogen fuel, flowing through the anode unit and reacting with the anode unit, where the anode unit comprises molybdenum oxide, and the molybdenum oxide reacts with the organic liquid hydrogen fuel to form hydrogen molybdenum bronze. The anode unit is a membrane structure. The anode unit comprises a first surface disposed on the proton exchange membrane, a second surface opposite to the first surface, and channels (121) disposed on the second surface. The fuel cell stack device further comprises a first bipolar plate (102) disposed on the anode unit. The first bipolar plate has a fifth surface disposed on the second surface, a sixth surface opposite to the fifth surface, and channels (103) disposed on the sixth surface. The fuel cell stack device further comprises an oxidant flowing through the channels on the sixth surface. The fuel cell stack device further comprises a second bipolar plate disposed on the cathode unit. An INDEPENDENT CLAIM is included for a manufacturing method for a membrane electrode assembly, involving: providing an anode unit comprising molybdenum oxide; putting a ring pad on the anode unit; pouring a resin solution comprising perfluorosulfonic acid in the ring pad; and drying the resin solution comprising perfluorosulfonic acid on the anode unit to form a proton exchange membrane on a surface of the anode unit; or putting a proton exchange membrane on the base of a pressing mold; covering the proton exchange membrane with a powder comprising molybdenum oxide; pressing a pressing element of the pressing mold on the powder and the proton exchange membrane with heat; and forming an anode unit of the powder after the powder is solidified.
