REGENERATIVE ELECTRODE MODULE OF FUEL ELEMENTS Russian patent published in 1996 - IPC

FIELD: regenerative energy converters built around fuel elements. SUBSTANCE: regenerative fuel module has several alternating fuel and electrodialysis elements incorporating anode and cathode chambers relatively spaced apart through 90 deg. , ion-conducting diaphragms based on solid electrolyte which contact metal anode and cathode made of different metals, placed in case accommodating pipe connections and header chambers for feeding and discharging reagents. Fuel and electrodialysis elements are combined in several alternating modules isolated by sealing gaskets; ratio of quantity of electrode chambers in fuel and electrodialysis modules is 2:1 to 3: 1. Electrodialysis and fuel modules may be stacked on adhesive by electrode chambers formed by opposite walls, inserted in each other, and secured over edge by through-shaped electrode and ion-conducting diaphragm based on solid electrolyte. Cathode chamber of electrodialysis module has catalytic cathode and diaphragm based on solid electrolyte, such as zirconium dioxide and calcium carbonate; anode chamber of mentioned module has catalytic anode and diaphragm based on solid electrolyte, such as lithium alumosilicate; perforated cathode and anode are made of different materials. EFFECT: improved design. 3 cl, 5 dwg
