Abstract:

This program is to investigate fuel cells for short duration, high intensity electrical power pulses. Equations describing fuel cell response were programmed for numerical solution. Studies showed the optimum system depending on required energy output and the importance of design configuration for removing heat from electrodes at high power density. Step load tests were conducted using low temperature H2-O2 cells with porous electrodes and aqueous potassium hydroxide electrolyte. Current peaks up to 9200 ampssq ft and power peaks up to 3750 wattssq ft were recorded. Near peak outputs were maintained for up to 800 micro-seconds. Power dropped back to one half peak levels in 5-300 milliseconds depending on conditions. Repeated pulse tests were conducted at frequencies of 10-10,000 cyclessecond, pulse durations of 20-95 and amplitudes up to 3600 ampssq ft. Improvements of up to 100 in power density were recorded while operating the cell in a pulsing mode.
