| Popis: | Heat recovery from the fuel-cell-stack cooling system is very important from the viewpoints of high total efficiency and also controling the temperature of the fuel-cell-stack. It is very difficult to control the fuel-cell-stack temperature, so the fuel-stack coolant temperature should be kept constant both to maintain high electrical efficiency and to prevent the fuel cell from deteriorating. The aim of this paper is to discuss the dynamical characteristics of fuel-cell-stack cooling system and to propose the simple dynamic model for designing the temperature control system and heat recovery system. Consequently, the simple lumped parameter dynamic model of the fuel-cell-stack cooling system is proposed and the validity of the model is confirmed by the experiment. |
