Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
135 words
A CELL FOR GENERATING ELECTRIC VOLTAGE WHICH COMPRISES IN COMBINATION A CONSUMABLE ANODE AND, A CATHODE COMPRISING A POROUS DIFFUSER, SAID DIFFUSER HAVING MEANS FOR CIRCULATING GASEOUS DEPOLARIZER THROUGH SAID DIFFUSER A LAYER OF INERT POROUS CARRIER MATERIAL BETWEEN SAID ANODE AND CATHODE SO THAT SAID NODE AND CATHODE HAVE SURFACES WHICH FACE EACH OTHER AND ARE SEPARATED FROM EACH OTHER BY THE CARRIER MATERIAL, MEANS FOR CIRCULATING ELECTROLYTE IN A SEPARATE AND DISTINCT PATH FROM SAID CIRCULATING DEPOLARIZER THROUGH SAID POROUS CARRIER MATERIAL AND MEAN FOR MAINTAINING THE DISTANCE BETWEEN THE FACING SURFACES OF SAID ANODE AND CATHODE CONSTANT DESPITE THE CONSUMPTION OF THE ANODE BY COMPRESSION OF SAID CELL IN A MANNER WHEREBY BOTH SAID ELECTRODES MOVE TOWARD EACH OTHER AT A RATE SUBSTANTIALLY EQUAL TO THE RATE OF CONSUMPTION OF SAID ANODE.
