Original NASA caption:

"Spacecraft technicians check the fuel cell in the adapter section of the Gemini VII spacecraft. Three modules each containing 32 individual sections are combined with appropriate control devices to make one fuel cell battery with a rated output of one kilowatt. Two of these batteries, each measuring 25 inches in length and 12.5 inches in diameter, provided on board electric power for the Gemini V eight day space mission."
