Fuel cells and batteries were discussed as power sources for the Gemini-Titan (GT) 5 mission (long-duration) at a meeting of the Gemini Management Panel.

A study was reviewed that proposed a combination to be used in the following manner: batteries would be used during peak load requirements; the fuel cell would supply the remaining mission power source requirements. The panal accepted the proposal, and McDonnell was directed to proceed with the plan. In addition, the group decided to remove the fuel cell from GT-4 and substitute batteries, pending the concurrence of NASA Headquarters. It also decided to fly older versions of the fuel cell in GT-2 (the redesigned version would be flown in the later manned flights) to gain flight experience with the component.
