摘要

The recent interest in and development of catalytic fuel cells for the generation of electricity from hydrogen-oxygen reactions, using alcohol as the propellant, has also advanced the status of solid polymer electrolytes, (ref 1). These electrolytes can also be used in reverse, in which power is applied to the cell, together with water, resulting in the electrolysis of the water into hydrogen and oxygen. In earlier treatments of spacecraft propulsion systems based on water electrolysis, (ref 2, 5), the hydrogen and oxygen were separated at the cell, and recombined in a bipropellant thruster downstream. However, in this paper the gases are allowed to mix in the cell, and are treated as a monopropellant, thereby simplifying the system design.rnThe propulsion system discussed in the paper is therefore based on the development of two new components. These are: a water electrolysis cell, capable of converting water into a hydrogen and oxygen mixture with reasonable efficiency; and a monopropellant thruster and inlet valve, the thruster being fitted with a spark generator and a flame holder.rnThis paper describes the water electrolysis system and compares its overall performance against conventional hot and cold gas chemical propulsion systems.
