Abstract: An operating method is disclosed for a dehydrogenation reaction system. The method includes providing a system having: an acid aqueous solution tank including an acid aqueous solution; a dehydrogenation reactor including a chemical hydride of a solid state and receiving an acid aqueous solution from the acid aqueous solution tank to react the chemical hydride with the acid aqueous solution to generate hydrogen; and a fuel cell stack receiving hydrogen generated from the dehydrogenation reactor to be reacted with oxygen to generate water and simultaneously to generate electrical energy. The method also includes recycling the water generated from the fuel cell stack to one or all of the acid aqueous solution tank, the dehydrogenation reactor, and a separate water tank. The acid is formic acid and, in in the dehydrogenation reactor, the temperature is in a range of 10° C. to 400° C. and the pressure is in a range of 1 bar to 100 bar.
