Power systems which use chemical fuel as the energy source appear useful in a variety of space applications and offer weight advantages for durations below about 100 hours. This volume discussed primary and secondary batteries, primary and regenerative fuel cells, reciprocating engines using hydrogen and oxygen bipropellant, monopropellant and bipropellant turbines and cryogenic storage of hydrogen and oxygen. The theoretical and practical performance of the converters is reviewed, and the weight of various systems is predicted. Other factors besides power system weight may lead to the selection of a chemical system in preference to others. For example, liquid hydrogen provides an excellent heat sink for environmental control. While batteries may be approaching the limits of their capability, major advances still will be accomplished in the fuel cell and dynamic engine area. For durations of more than several hours primary system weights of 1 to 1.5 lb/hp hr and secondary specific weights of up to 100 whr/lb appear possible by 1970.
