THIN FUEL CELL ELECTRODES.
Abstract
Fifteen, 100-watt (nominal), hydrogen-air batteries were built and subjected to various load and environmental conditions. The results now allow us to predict the performance and life expectancy of such batteries. Current densities as high as 100-ASF continuous loading could be supported without electrode damage. Of particular interest was the study of the interdependence of air humidity, gas flow rates, temperature, electrolyte concentration, and current density. The effects of incomplete-CO2 removal from the air, the differences between KOH and NaOH as electrolyte, and the characteristics of oxygen and air operation were determined. Optimum steady-state conditions for longest life were outlined, and it was shown that this type of battery is capable of extended operation with a minimum of maintenance. The uniformity of multicell batteries was carefully checked, and is discussed in detail. (Author)
