What else can I help you with?
Did Apollo 11 have solar cells?
None of the Apollo spacecrafts has solar cells. All of them used fuel cells and chemical batteries to provide energy.
What are the alternatives to batteries for powering electronic devices?
Some alternatives to batteries for powering electronic devices include solar power, kinetic energy, fuel cells, and wireless power transfer technologies.
What are some alternative power sources that can be used instead of batteries?
Some alternative power sources that can be used instead of batteries include solar power, wind power, hydroelectric power, and fuel cells.
What fuel was used in torches before batteries?
Kerosene was a common fuel used in torches before batteries.
How do solar cars work during the day?
Solar cars gain energy from the sun or wind to make fuel or power that have been stored in their batteries or fuel tanks. They use the power in their batteries or fuel tanks to run during the day!
How are fuel cells different from conventional batteries in terms of their energy storage and conversion mechanisms?
Fuel cells differ from conventional batteries in their energy storage and conversion mechanisms. While batteries store energy in chemical form within the cell, fuel cells generate electricity through a chemical reaction between a fuel source and an oxidizing agent. This allows fuel cells to continuously produce electricity as long as fuel is supplied, unlike batteries which have a limited capacity and need to be recharged.
Are solar batteries commonly used by NASA?
Solar cells are commonly used on spacecraft but because a spacecraft might spend a considerable amount of time in the dark they also have fuel power. They most obviously use oil based fuel to launch the spacecraft into space.
What are the similarities between batteries and fuel cells?
Cathode is positive and anode is negative for both.... we cant say both are not rechargeble ..... but using electricity we cant recharge dry batteries (some) and fuel cells...
What kind of fuel does the solar car use?
The fuel a solar car uses is energy from the sun converted into electricity using solar cells.
What type of electric current is produced by fuel cells and solar cells?
ac
Why are fuel cells used on the space shuttle instead of batteries?
Two reasons:Weight. Batteries are heavier per energy unit than fuel cells.Capacity. Fuel cells can store much more energy than batteries.As a bonus, the weight for the fuel cell fuel reduces the weight of another required consumable: water. The "exhaust" of fuel cells is pure water which astronauts can drink.
What are the elements that can produce electricity?
Some elements that can produce electricity include lithium, silicon, copper, and zinc. These elements are commonly used in batteries, solar panels, and fuel cells to generate electrical power.
