Abstract
As the dependency on the non-renewable energy sources is increased and the environmental concerns are illuminated, research on zero emission energy sources such as PEM fuel cell has been intensified. One of the main hurdle to commercialize PEM Fuel cell as a main energy source in automobile application is the degradation (Aging) of the fuel cell. In order to reduce fuel consumption and fuel cell degradation in Fuel Cell Electric Vehicles, effective distribution of power demand between Fuel Cell and Battery is required. The energy management strategies can improve fuel economy and or fuel cell aging by meeting power demand efficiently. Concerning development and or evaluation of energy management strategies, ultimate limits of improvement of the fuel cell stack aging for the given drive cycle needs to be known. There are several methods researched to calculate ultimate limit of fuel cell stack aging reduction for given drive cycle.[1] Here in this paper `Dynamic Programming' approach for calculating ultimate limit for improvement of fuel cell stack aging has been applied. The influence of maximum power of the battery on fuel cell stack aging and battery aging, using dynamic programming as optimizer has been evaluated. The Economic advantage while using different size of battery and fuel cell stack has been calculated in this paper.
