Abstract
A hydrogen fueled power system of a vehicle includes a liquid hydrogen fuel source having a volume of liquid hydrogen fuel, and a thermal engine configured to expand the liquid hydrogen fuel into gaseous form via interaction between a heated first portion of the hydrogen fuel and a second portion of the hydrogen fuel. A heat exchanger is located between the liquid hydrogen source and the thermal engine. The heat exchanger is configured to heat the first portion of the hydrogen fuel via thermal energy exchange with a relatively warm fluid. A power generator is positioned fluidly downstream of the thermal engine. The power generator utilizes exhaust from the thermal engine to generate electrical or mechanical power.
