In developing new generation vehicles, the fuel cell hybrid vehicle has become more important as environmental standards become more stringent. This paper details the Fuel Cell Hybrid Radio Control Car (FCHRC) with proton exchange membrane fuel cell stack(75×55×65mm, 6V, 5A) and a secondary battery(7.4V, 2A) charged up by a solar cell(61mm x 110mm, 1.7V, 450mA). The design work of the FCHRC was made progress by CATIA modeling & assembling before manufacturing it. In this paper, we will focus on the automatic conversion of a power source between the PEMFC and the secondary battery, and finding the optimum conditions (temperature, humidity, airflow rate and hydrogen pressure) through thousands of performance tests in the humidity-temperature program controller. The purpose is that the models and data from the experiments we conducted will contribute to the ongoing development of the fuel cell hybrid car.
