#### Abstract

From wood to coal and petroleum, mankind has used various fuel. Since using such fuel, mankind has developed power source of mechanism. We obtain numerous power from caloric force. Present energy supply is based on the fossil fuel. Fossil fuel has high energy density and is convenient for transportation and storage. Human being prepared countermeasure of energy economy, high energy efficiency and substitution energy for limits of fossil fuel. High energy efficiency among them is very important. This research will improve total output by physical exergy recovery of $LH_2$-fuel cell system.
