McDonnell issues a $9 million subcontract to General Electric to design and develop fuel cells for the Gemini spacecraft. The General Electric design, selected by the Manned Spacecraft Center after an analysis completed January 23, appeared to offer advantages over the competing solar cells or other fuel cells in terms of simplicity, weight, and compatibility with other Project Gemini requirements. Much of this advantage is credited to the use of ion-exchange membranes rather than gas-diffusion electrodes within the fuel cells.

Author: Project Gemini Chronology

The Project Gemini Chronology is drawn from multiple sources, but most heavily from NASA's Special Publication-4002, Project Gemini Technology and Operations: A Chronology, prepared by James M Grimwood and Barton C Hacker, with Peter J Vorzimmer.
