Verfahren und Vorrichtung zum UEberwachen und Regeln der Konzentration von Hydrazin in einem Brennstoffelement

摘要

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.
