Abstract

We considered the concepts of combined power plant (PP) for the aviation and space rocket technology consisting of an oxygen- hydrogen (O2/H2) electrochemical generator (ECG) and a controlled hydrogen generator based on hydronic chemical current source (CCS) with an aluminum anode. Their advantages and disadvantages are shown. The theoretical calculations of power and current- voltage characteristics of PP are executed. A preliminary estimation of parameters of controlled hydrogen generator based on the hydronic CCS for O2/H2 ECG with nominal power of 1 kW is developed. The calculation showed that on the basis of hydronic CCS with an aluminum anode it is possible to create a hydrogen generator with electrochemical control of its escape rate in a wide range. It was first shown that the application of a combined PP is safe and effective solution of the problem of hydrogen storage for autonomous PP as space and terrestrial applications.
