Which type of battery has been designed for use in space vehicles?

Question

Quizplus · Accepted Answer

Fuel cells are the best choice for use in space vehicles as they have higher specific energy (energy per unit weight) compared to other types of batteries. They also produce clean energy (water vapor) and do not generate pollutants that could contaminate the spacecraft environment. Lead storage batteries are heavy, bulky, and have a limited life cycle. Alkaline dry cells are cheaper but have a limited operating temperature range. Mercury cells are toxic and have been phased out due to environmental concerns. Silver cells, although lightweight and powerful, have a high cost and are sensitive to temperature changes.
