Abstract
By utilizing in a multi-layered fuel cell, plastic separators with the inter-cell connectors supported in resilient but vaportight fashion within the separators, a lighweight fuel cell may be realized which does not suffer from fuel-oxidizer leakage despite temperature rises and accompanying differential component expansion.
Claims10
A multi-layered fuel cell including:
- a plurality of adjacent unitary cells each including an anode and a cathode;
- a plastic, gas-impermeable separator physically separating the anode electrode of one of said plurality of cells from the cathode electrode of the adjacent cell in said plurality;
- a plurality of conductors extending through said separator and flexibly supported therein by elastic, gas-tight seals;
- said conductors interconnecting, electrically, said anode electrode of one of said unitary cells to said cathode electrode of the next succeeding cell in said plurality;
- a chamber for electrolyte formed, at least in part, by the anode and cathode electrodes of each unitary cell;
- housing means for supporting said unitary cells in fixed relationship with respect to each other;
- means for introducing fuel and oxidizer gases to said unitary cells;
- and,
- means for extracting electricity from said plurality of unitary cells.
