FUEL CELL/GAS TURBINE HYBRID POTX

The critical engine/fuel cell integration challenge is the development of a recuperatorcapable of accepting gas-inlet temperatures in excess of 1740oF, well beyond thecapability of superalloys in this service. The design concepts developed in this study relyon the use of the adv[r]

1.2 Challenges for the Further Development of Fuel CellsThe first fuel cell was invented by William R. Grove in 1839 and it was called“gaseous voltaic battery”. The setup included two platinum electrodes coveredwith inverted tubes which were halfway submerged in a beaker of aque[r]

The beauty of powering cars with electricity from the grid is that we can generate the electricity any way we want without changing the cars. As we have seen, we can generate electricity with our choice of fossil fuels. We can also use nuclear fuel, or we can generate it with any of a number[r]

hybrid architecture. This is the fuel cell vehicle (FCV). The following rationale is to justify FCVs absence in Fig. 3 and in the rest of this chapter. The hydrogen-based chemical reaction of FCVs generates the electricity either to be used by the EM or stored in battery or supe[r]
