1. A solid state hydrogen compressor, comprising:
at least one membrane fixed between two porous electrodes, together forming a membrane electrode assembly;
a pair of cell plates or bipolar plates, between which the membrane electrode assembly is clamped;
wherein the membrane has a larger area than the porous electrodes and protrudes outside an area of the porous electrodes; and
wherein the cell plates have a larger area than the membrane and protrude outside an area of the membrane;
two insulating gaskets,
each surrounding one of the porous electrodes;
covering the part of the membrane that protrudes outside the region of the electrodes; and
protruding outside the area of the membrane;
wherein a single reinforcement layer is arranged between the insulating gaskets, completely radially outside a radial edge of each electrode;
wherein the reinforcement layer has a first thickness;
wherein the insulating gaskets have a second thickness;
wherein the insulating gaskets are formed as annular rings;
wherein each respective insulating gasket comprises a first through hole passing through the center of the respective insulating gasket to form a respective annular ring;
wherein each respective insulating gasket comprises a second through hole radially outside the first through hole and arranged in the material forming the annular ring of the respective insulating gasket;
wherein the second through hole of each respective insulating gasket is concentric with through holes formed in each cell plate for the passage of coolant;
wherein the solid state hydrogen compressor comprises a round cross section;
wherein the membrane, the electrodes, and the cell plates each comprise a round cross section and the insulating gaskets and the reinforcement layer each comprise a ring shaped cross section; wherein the insulating gaskets extend beyond the membrane on either side of the membrane in the direction facing away from the porous electrodes; and wherein the single reinforcement layer directly abuts both the insulating gaskets.
