This project discussed the technical feasibility and comprehensive utilization of resources and energy on Mars, which may have applications in the Mars exploration. Renewable fuel cell system could convert solar energy into chemical energy, electric energy and heat energy with the medium of recycled water, hydrogen and oxygen. In this project, a renewable energy system was designed based on fuel cell and water electrolyzer. Thereafter, the performance of the regenerative fuel cell was tested. The result shows that the power generation efficiency of the regenerative fuel cell was 65.41%, and the electrolysis efficiency was 90.2%. Meanwhile, the purity of hydrogen and oxygen were over 99.99% and the conductivity of water was lower than 5.0μS/cm.
