Abstract
A method for the production of an electrochemical cell and an electrochemical cell stack is disclosed with annular electrolyte arranged in a pressure vessel. Such a cell is produced by providing an annular precursor already provided with the electrodes where the product is converted to the desired membrane/electrolyte by heating and oxidation. By using a pressure vessel, pressure can also be generated during the conversion. To this end the region outside the cell is provided with a fill material. A number of cells can be stacked on top of one another. With this arrangement, the anode of one cell can act as cathode of another cell by means of a Z-shaped configuration. Adjacent anodes/cathodes can be applied to one another by welding or can be of a Z-shaped design.
Claims4
A stack of electrochemical cells comprising a plurality of cells wherein each cell comprises:
- an annular porous platinum anode;
- an annular porous platinum cathode;
- and
- a precursor to an annular membrane disposed between said anode and said cathode, said precursor consisting of zirconium metal alloy, wherein:
- an anode of a cell in said plurality of cells is directly connected to a cathode of an adjacent cell in said plurality of cells;
- and
- said stack includes an internal heating element.
