What are the main differences between fuel cells and batteries in terms of their efficiency and environmental impact?
Fuel cells are more efficient than batteries because they convert fuel directly into electricity without the need for charging. They also have lower environmental impact as they produce fewer emissions and pollutants compared to batteries which rely on chemical reactions.
How does a fuel cell differ from other types of cells?
A fuel cell differs from other types of cells, such as batteries, in that it generates electricity through a continuous chemical reaction rather than storing energy. Fuel cells convert the chemical energy of a fuel (typically hydrogen) and an oxidant (usually oxygen) directly into electrical energy, producing water and heat as byproducts. Unlike batteries, which require recharging after their stored energy is depleted, fuel cells can operate as long as they are supplied with fuel and oxidant. Additionally, fuel cells are often more efficient and environmentally friendly compared to traditional combustion-based power sources.
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 is the use of nickel oxide?
Some applications of nickel oxide (NiO) are: catalysts, ceramics, steels, batteries, fuel cells, etc.
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.
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.
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...
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 powered the Apollo 11 spacecraft?
The spacecraft's electrical power came from storage batteries (also called fuel cells), carried onboard. They generated a maximum of about 2300 watts. The fuel to launch the spacecraft was liquid oxygen (with kerosene, and liquid hydrogen for the upper stages), with nitrogen tetroxide to steer, adjust and make course corrections.
What are the main differences between fuel cells and batteries in terms of their efficiency and environmental impact?
Fuel cells are more efficient than batteries because they convert fuel directly into electricity without the need for charging. They also have lower environmental impact as they produce fewer emissions and pollutants compared to batteries which rely on chemical reactions.
What powered Apollo 13?
Apollo 13 was powered by a combination of fuel cells and batteries. The primary source of power for the spacecraft was from three hydrogen-oxygen fuel cells, which generated electricity by combining hydrogen and oxygen in a chemical reaction. In addition to the fuel cells, there were also batteries on board that provided backup power.
What was Apollo 13s power soruce?
Apollo 13's power source was primarily provided by fuel cells that converted hydrogen and oxygen into electricity. These fuel cells were essential for providing electricity to the spacecraft for various systems and experiments. In addition to the fuel cells, Apollo 13 also had batteries as a backup power source in case of any malfunctions.
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.
Food fuel and batteries go through storage tanks physical changes chemical changes inertia what is the right answer?

Is a fuel cell a secondary cell?
No, a fuel cell is not considered a secondary cell. Fuel cells generate electricity through a chemical reaction involving a fuel source and an oxidizing agent, without the need for recharging like secondary cells, such as batteries.
What battery does NASA use for their space shuttles?
They get electricity through the use of fuel cells. not batteries. The current limiter to the length of a mission is the amount of hydrogen and oxygen carried to use in the fuel cells.
What do fuel cells batteries and solar cells have in common?
They all produce static electricity.
