A Methane Fuel-Cell Power Unit for Titan Surface Stations: Reactant Rates and Stack Sizing

This study sizes the Titan surface system named in its title for operation in the Titan surface environment, and reports the result as SIMULATED, NOT MEASURED. The design is developed from stated physical relations and a shared environmental basis, and every performance figure is computed by the deposited script rather than asserted. Among the computed results are stack current of 694.4 amperes, methane consumption of 1.47 kilograms per day, oxygen consumption of 5.85 kilograms per day. Mass and power budgets are assembled from components so that they can be audited, off-design behaviour and materials uncertainty are discussed openly, and the limits of the sizing are stated in full. The fuel cell is a civilian power unit for science stations and habitats; it burns lake methane with stored oxygen to make electricity and water, and has no application beyond supplying peaceful surface infrastructure.
