Accordingly, the research and development of new energy source has become a crucial subject for all of the countries in the world. The large number of transportation has become the one of pollution in the city. Therefore, a lot of countries make the laws in order to develop electronic vehicle which has no pollution. This study in design the combination of the solar can with the proton exchange membrane fuel cell system lit it become the double electronic carries. It included the dispose of fuel cell system, the set of double electronic power, the set of store hydrogen bottle number, the design of booster stander, the choice of fuel cell and so on. This study focused on the performance test and the function from selected full cell system. The test found out the function of fuel cell system was stable. At the same electric current, the output voltage value was ±0.5 volts. The testing result showed that increasing hydrogen pressure can not increase performance; however, it lost hydrogen. The increasing hydrogen temperature can increase the performance of fuel cell but the result does not meet with the ideals. It is efficient to produce under 80°C, but the efficiency is still decreasing. The testing result showed that the hydrogen consumption rate, the discharge capacity, the temperature of stack and the average degree will increase with the increasing of electric current. About the hydrogen consumption rate and discharge capacity, they raised straight with the increasing of electric current. In addition, the temperature of stack and the average degree raised straight under 0~35A; however, it showed stable under 40~50A due to the heat slit above the stack. The result indicated that the temperature of the above surface stack is higher than the temperature of the below surface temperature.
