Abstract
A hydrogen fuel system in which the fuel is transformed from liquid to gas is used to administer cooling, e.g., air conditioning. The system incorporates first and second stage heat exchangers. The first stage exchanger is used to benefit from the endothermic reaction created when liquid hydrogen transforms into gas. The cooling provided from this state change is transferred into a second medium which is delivered into a second stage heat transfer device and then used for cooling purposes.
