As part of an electric vehicle state-of-the-art evaluation, General Motors built a fuel cell powered van, the Electrovan, to explore the potential and problems of the fuel cell powerplant. Fuel cells were considered because they offer the potential of high thermal efficiency and extended range compared with batteries. Although the Electrovan was successfully operated on the road, we concluded that much research and development work is still needed to solve the many major problems. The encouraging rate of progress and the advantages of fuel cells provide the stimulus to maintain a strong continuing effort in this field.
