Novel alkaline electrolytic reactor and application

The invention relates to the technical field of renewable energy utilization, in particular to a novel alkaline electrolytic reactor and application. The novel alkaline electrolysis reactor comprises a protection cavity; the alkaline electrolysis pile is arranged in the protection cavity; the protection cavity has n layers, the pressures of all the layers are different, the layer closest to the alkaline electrolysis stack is the nth layer, and the pressure of the space formed by the nth layer and the alkaline electrolysis stack is Pn; the protective cavity on the outer side of the nth layer is the (n-1) th layer, and the space pressure formed by the protective cavity and the nth layer is Pn-1; by parity of reasoning, the outermost protection cavity is the first layer, the outer side of the first layer is the atmospheric environment, and the pressure is P0; the internal pressure of the alkaline electrolytic reactor is the pressure Pstack of the electrolytic reaction; pstack < gt >; pngt; Pngt; pn-1gt; ... gt;
