[0001] This invention relates to a type of battery device, and in particular to a stackable hydrogen fuel cell device in which a hydrogen fuel box and a battery control box are stacked on top of each other to generate electrical energy from hydrogen fuel, store the electrical energy in a hydrogen energy generating battery, and then supply the electrical energy from the battery to the battery control box for reuse. A fuel cell is a power generating device that converts chemical energy in fuel into electrical energy, mainly through the oxidation-reduction reaction of oxygen or an oxidant, and the most commonly used fuel is hydrogen.
