Abstract
A parallel fuel cell electrical power system is provided. The parallel fuel cell electrical power system includes a plurality of fuel cell electrical power modules and a direct-current bus (DC bus). Each of the fuel cell electrical power modules has a fuel-cell stack, a current switch, and a reverse current protection element. The DC bus electrically connects the output end of the plurality of fuel cell electrical power modules and makes one fuel cell electrical power module electrically connect to another fuel cell electrical power module in parallel, such that the fuel-cell stacks with a fixed power capacity are combined to effectively output a variety of voltages for a load.
