The objective of this program is to develop the technology required for a High Performance Fuel Cell System for future Air Force manned earth-orbiting space vehicles. A system centerline design was established including design requirements specifications for the performance, allowable weights, parasitic power, and failure rates necessary to meet the energy-to-weight, reliability and other requirements of the contract Statement of Work. The system design is based on the use of Allis-Chalmers capillary-type fuel cells with Static Moisture Removal and direct internal liquid cooling. The coolant FC-75 was selected for the centerline design by means of an analysis which compared various candidate coolants on the basis of pumping power requirements and materials compatibility. Effort was initiated to develop optimum coolant manifolding through the fuel cell stack. Research was initiated toward the goal of achieving the required fuel cell performance and light weight fuel cell stack construction. Detailed design of initial breadboard-type, four-cell experimental units was performed, and fabrication for the first two units was initiated. Author
