A unique requirement of underwater vehicles' power/energy systems is that they remain neutrally buoyant over the course of a mission. Previous work published in the Journal of Power Sources reported gross as opposed to neutrally-buoyant energy densities of an integrated solid oxide fuel cell/Rankine-cycle based power system based on the exothermic reaction of aluminum with seawater. This paper corrects...
This work investigates the integration of solid oxide fuel cells with a novel underwater propulsion system based on the exothermic reaction of aluminum with seawater. The purpose of the fuel cell is to increase the overall thermodynamic efficiency of the system and consume waste hydrogen produced by the aluminum–water reaction. The system is modeled using a NASA-developed framework, Numerical Propulsion...
