Bendable inorganic solid electrolyte membrane and membrane electrode, sodium fuel cell single body and metal sodium regeneration unit formed by same

The invention relates to the technical field of electrochemistry, to be specific, relates to a bendable inorganic solid electrolyte membrane and a membrane electrode, a sodium fuel cell single body and a metal sodium regeneration unit formed by same. The bendable inorganic solid electrolyte membrane comprises inorganic solid electrolyte sheets and adhesive, wherein a plurality of inorganic solid electrolyte sheets are in a plane-shaped arrangement, and the adhesive is disposed in gaps among the inorganic solid electrolyte sheets in a filled manner. By using the viscosity of the adhesive, the inorganic solid electrolyte sheets are connected into a large-area membrane. By using the elasticity of the adhesive, impact stress of external force on the inorganic solid electrolyte sheets can be buffered, and the prepared large-area membrane can be bent and deformed. By using the insulation performance and the sealing performance of the adhesive, the prepared inorganic solid electrolyte membrane has electronic insulat
