A description of the efforts to apply fuel cells to electric propulsion systems is given. Early assessments of the feasibility of using fuel cells in highway transportation applications are reviewed, and the results of performance studies based on these assessments are given. The present state-of-development of phosphoric acid and SPE fuel cells is discussed with respect to the vehicular application. Fuel cell vehicle power requirements and operational considerations are updated. Models are being developed that include the dynamics of the fuel cell stack and fuel processor in order to determine if duty cycles, for example the UDS, can be met. Experiments have indicated that methanol fuel processors with contemporary designs have very long time constants and could not conceivably meet vehicular transient requirements. Analysis indicates that a reformer could be designed with fairly fast transient capability, and work is being done in this area.
