EXERGY ANALYSIS OF POWER SYSTEMS FOR CLEAN ENERGY VEHICLES

Recently various energy systems for clean energy vehicles have been developed such as an alternate fueled system, an electric powered system, a fuel cell system, etc. It is insufficient to evaluate the performance or the environmental impact only with energy analysis for the newly developed energy systems. Then the authors would propose the exergy analysis for the energy systems. To improve the power systems it will be important to know which element of the system is the bottleneck of exergy flow. For example, a fuel cell hybrid vehicle consists of an internal combustion engine, a vaporizer, a reformer, and a fuel cell. In the reformer, hydrocarbon with steam is reformed to hydrogen by endothermic reaction. In the fuel cell, electromotive power is generated with hydrogen and oxygen in air. In the engine, mechanical output is obtained with combustion heat of fuel. If the exergy efficiency would remarkably decrease in the reformer, the reformer should be modified. The authors have compared two energy systems on the basis of the energy analysis of conventional internal combustion engines, and have evaluated the whole powered systems.
