Abstract
An electric power generating system includes a cell such as a fuel cell for outputting direct-current power and a conversion device having at least either one of an inverter for converting the direct current power into alternating-current power and a converter for changing a voltage level of the direct-current power. The cell generates high-temperature thermal energy of 60.degree. C. or higher in association with the generation of direct-current power. The conversion device employs a semiconductor element capable of operating at an ambient temperature of 55.degree. C. or higher. The semiconductor element may be an element having a wider band gap than Si. Further, the conversion device may employ a GaAs semiconductor element, an InP semiconductor element, an SiC semiconductor element, a GaN semiconductor element or combinations thereof.
