Abstract

The invention provides a space hydrogen-oxygen fuel cell hybrid energy system. The system comprises a fuel cell, a DC / DC converter and a lithium ion storage battery pack; the output end of the fuel cell is connected with the input end of the DC / DC converter, and the output end of the DC / DC converter is connected with the load; the fuel cell is used for generating electric energy by adopting hydrogen and oxygen as raw materials; the DC / DC converter is used for regulating and controlling the electric energy output to the load by the fuel cell; the output end of the DC / DC converter is further connected with the lithium ion storage battery pack, when the energy requirement of the load is higher than the electric energy output of the fuel battery, the lithium ion storage battery pack provides necessary peak power output for the load, and when the energy requirement of the load is lower than the electric energy output of the fuel battery, the lithium ion storage battery pack receives the electric energy output by the DC / DC converter for charging. The space fuel cell hybrid energy system can realize 1kW@48h power output and has the characteristics of clean and pollution-free products, high energy density and the like.

Description

technical field [0001] The invention relates to the technical field of space fuel cells, in particular to a space hydrogen-oxygen fuel cell hybrid energy system. Background technique [0002] With the continuous development of space exploration and manned space missions, higher performance requirements are put forward for space power supply technology. As a very important space power supply technology, fuel cell technology can directly convert the chemical energy contained in fuel and oxidant into electrical energy electrochemically. Hydrogen-oxygen fuel cells use pure hydrogen and pure oxygen as reactants, and its products are only water and heat energy. It can be effectively compatible with the power system and propellant system in spacecraft, and has a good application prospect in space engineering. [0003] There are some researches and applications on hydrogen-air fuel cell power systems for ground use, but there is little international research on hydrogen-oxygen fuel...
