Claim 5:
6. The oxygen delivery system of claim 1, wherein the power generation subsystem comprises one or more one fuel cell modules for a clean fuel vehicle, the one or more fuel cell modules comprising:
a plurality of hydrogen fuel cells in fluid communication with one or more fuel tanks, one or more heat exchangers or expansion units, and one or more oxygen delivery apparatus of the oxygen delivery system;
each hydrogen fuel cell of the plurality of hydrogen fuel cells comprising:
a hydrogen flowfield plate, disposed in each hydrogen fuel cell, and comprising a first channel array configured to divert gaseous hydrogen (GH2) inside each hydrogen fuel cell through an anode backing layer connected thereto and comprising an anode gas diffusion layer (AGDL) connected to an anode side catalyst layer that is further connected to an anode side of a proton exchange membrane (PEM), the anode side catalyst layer configured to contact the GH2 and divide the GH2 into protons and electrons;
an oxygen flowfield plate, disposed in each hydrogen fuel cell, and comprising a second channel array configured to divert compressed air inside each hydrogen fuel cell through a cathode backing layer connected thereto and comprising a cathode gas diffusion layer (CGDL) connected to a cathode side catalyst layer that is further connected to a cathode side of the PEM, wherein the PEM comprises a polymer and is configured to allow protons to permeate from the anode side to the cathode side but restricts the electrons;
an electrical circuit configured to collect electrons from the anode side catalyst layer and supply voltage and current to vehicle components, wherein electrons returning from the electrical circuit combine with oxygen in the compressed air to form oxygen ions, then the protons combine with oxygen ions to form H2O molecules;
an outflow end of the oxygen flowfield plate configured to use the second channel array to remove the H2O molecules and the compressed air from each hydrogen fuel cell; and
an outflow end of the hydrogen flowfield plate configured to use the first channel array to remove exhaust gas from each hydrogen fuel cell, thereby disposing subcomponents inside each of the plurality of hydrogen fuel cells with flow vectors enabling the plurality of hydrogen fuel cells to be assembled into one or more fuel cell stacks aligned within the or more fuel cell modules forming a modularly combinable fault-tolerant unit.
