1. A liquid hydrogen (LH2) fuel storage system for a fuel cell-powered vehicle, comprising
a main LH2 storage fuel tank configured for close to ambient pressure storage of LH2, and one or more gas accumulator tanks (GATs) smaller than the main fuel tank and configured for elevated pressure storage of LH2 and for feeding pressurized LH2 to the fuel cell, wherein the one or more GATs each have a cooling interface configured to cool the GAT employing LH2 from the main fuel tank, and a heating interface configured to heat contents of the GAT with warm working fluid from the fuel cell-powered vehicle whereby to raise pressure of the LH2 in the GAT to a working pressure for feeding the LH2 to the fuel cell.
