Claim 0:
1. A hydrogen fueled power system of a vehicle, comprising:
a liquid hydrogen fuel source having a volume of liquid hydrogen fuel;
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 disposed between the liquid hydrogen source and the thermal engine, the heat exchanger configured to heat the first portion of the hydrogen fuel via thermal energy exchange with a relatively warm fluid;
a turbine disposed fluidly downstream of the heat exchanger and upstream of the thermal engine, the turbine driven by the heated first portion of the hydrogen fuel; and
a power generator disposed fluidly downstream of the thermal engine, the power generator utilizing exhaust from the thermal engine to generate electrical or mechanical power;
a compressor operably connected to the turbine, wherein the turbine drives operation of the compressor; and
a fluid separator disposed between the heat exchanger and the turbine to remove condensate from the first portion of the hydrogen fuel.
