摘要：

The relationship between power and energy for a fuel cell system consisting of a fuel cell stack and reactant storage subsystem, and operating at constant power or variable power, was analyzed. The characteristic parameters of the fuel cell stack and the reactant subsystem are considered to be independent variables, which are functions of the power and energy of the fuel cell system, respectively. Mathematical expressions were derived for determining the minimum weight of the fuel cell system when the cells operate at constant power and the cell voltage varies linearly with the current density. The relationship between the weight of a fuel cell system and variable power levels was also determined. These mathematical models were used to analyze the experimental results reported in the literature for an alkaline fuel cell and a polymer electrolyte fuel cell.
