Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
METHOD OF PERIODICALLY REMOVING INERT GAS ACCUMULATIONS FROM ELECTRO-CHEMICAL ENERGY CONVERSION CELLS HAVING ELECTRICALLY PARALLEL CONNECTED GAS-DIFFUSION ELECTRODES SERIALLY SUPPLIED WITH INERT-GAS-CONTAINING REACTION GAS, WHICH COMPRISES ELECTRICALLY MEASURING THE PARTIAL CURRENT OF THE LAST ELECTRODE IN THE SUPPLY SERIES AS A CRITERION, ELECTRICALLY OBTAINING A REFERENCE MAGNITUDE CHARACTERISTIC OF ELECTRIC OPERATING CONDITION OF THE ELECTRODE, ELECTRICALLY COMPARING THE PARTIAL CURRENT WITH SAID MAGNITUDE CHARACTERISTIC AND IN RESPONSE TO SAID COMPARISON AUTOMATICALLY BLOWING A RINSING FLOW OF GAS SERIALLY THROUGH THE ELECTRODES WHEN THE RESULTANT MAGNITUDE DEPARTS FROM GIVEN LIMITS.
Claim 2
Dependent Claim
89 words

Claim 3
Dependent Claim
137 words
IN ELECTRO-CHEMICAL ENERGY CONVERSION APPARATUS HAVING AN ELECTRIC LOAD CIRCUIT AND GAS-DIFFUSION ELECTRODES ELECTRICALLY PARALLEL CONNECTED TO SAID CIRCUIT AND GAS SUPPLY MEANS SERIALLY CONNECTED WITH SAID ELECTRODES FOR SUPPLYING THEM WITH INERT-GAS-CONTAINING REACTION GAS, THE COMBINATION OF A DEVICE FOR PERIODICALLY REMOVING INERT GAS ACCUMULATIONS FROM THE ELECTRODES COMPRISING CURRENT-RESPONSIVE CIRCUIT MEANS CONNECTED WITH SERIALLY LAST ELECTRODE RELATIVE TO SAID GAS SUPPLY MEANS, REFERENCE CIRCUIT MEANS CONNECTED TO SAID LOAD CIRCUIT FOR SUPPLYING A REFERENCE MAGNITUDE WHICH IS CHARACTERISTIC OF THE OPERATION OF THE APPARATUS, A COMPARATOR MEANS TO WHICH SAID TWO CIRCUIT MEANS ARE INPUTWISE CONNECTED, AND PRESSURE CONTROL MEANS DISPOSED IN SAID GAS SUPPLY MEANS AND CONNECTED WITH SAID COMPARATOR MEANS FOR PASSING A RINSING FLOW OF GAS THROUGH SAID ELECTRODES WHEN SAID PARTIAL CURRENT CHANGES TO A VALUE INDICATIVE OF INERT GAS ACCUMULATIONS.
Claim 4
