Fuel cells that use hydrogen as fuel consume little energy and emit only water. High expectations are placed on the fuel cell as a clean source of power for automobiles. However, various issues have to be solved before the fuel cell can be used in commercial products.
It is difficult to obtain pure hydrogen and pure oxygen. The Laboratory is undertaking research to improve the performance of fuel cell vehicles and to develop a suitable evaluation technique by analyzing the impact of impurities on the power generation performance of the fuel cells.
