Abstract: The disclosure describes a sensing cell which monitors hydrazine concentration in the fuel cell electrolyte by detecting the potential difference between (i) an anode which forms part of a complete circuit including a load and (ii) a reference anode, both anodes being in contact with the electrolyte. Also described is a hydrazine fuel cell which includes the improved anode and/or the sensing cell.

Abstract: A cathodic sensing cell is provided which monitors hydrazine concentration in the electrolyte of a fuel cell. The hydrazine in the electrolyte reacts on the surface of a depolarized cathode lowering the open circuit voltage of the cathode proportional to the amount of hydrazine present. This effect is used to regulate the hydrazine concentration in an operating hydrazine fuel cell.

Abstract: AIR-DEPOLARIZED CELLS ARE DISCLOSED WHICH HAVE AN IMPROVED AQUEOUS ELECTROLYTE. THE ELECTROLYTE, WHICH IS NEUTRAL, SLIGHTLY ACID, OR SLIGHTLY ALKALINE, CONTANS: (A) A SALT SUCH AS A HALIDE OF AN ALKALI METAL, ALKALINE EARTH METAL, ALUMINUM, ZINC, OR AMMONIA; AND (B) A CYANATE OR THIOCYANATE SALT. THE AIR-DEPOLARIZED CELLS OF THE INVENTION ALLEVIATE THE PROBLEM OF CARBONATION WITH ATTENDANT PLUGGING OF THE PORES IN THE CATHODE THAT IS OFTEN ENCOUNTERED WITH AIR-DEPOLARIZED CELLS UTILIZING STRONG ALKALINE ELECTROLYTES.
