Development of A Simulator to Evaluate Fuel Cell Systems

Abstract

The fuel cell has a special feature to convert chemical energy of fuel into electricity without use of a heat engine. In this paper, a method is proposed, in which energy conversion and exergy loss in the cell can be displayed on CRT by representing the relation between the amount of energy transformed and the energy levels of the energy donating process and energy accepting one on an Energy-Utilization Diagram (EUD). Also a simulator is developed to automatically generate EUDs by giving compositions and conditions of input streams, reactions in the cell and the exergy loss information.
