they give us energy
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.
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.
Chemical energy is stored in batteries, food, and other molecules. When these substances undergo chemical reactions, the stored energy is released.
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.
Chemical energy.
how are wood and battery energy alike
Kerosene was a common fuel used in torches before batteries.
physical changes
yes, in someways. Zinc can be the fuel for some batteries.
The food we eat contains chemical energy, which is released through digestion and metabolized by our bodies to fuel various processes. Batteries store electrical energy, which is converted into usable power when connected to a device or circuit.
Car batteries will make a larger explosion than flashlight batteries would.
it means it can run on batteries and gas
it means it can run on batteries and gas
The only similarities is that they both store electrical energy.

food chain and forest are amost alike because foog chain make a snowly energy
Carnivores and Omnivores are alike because they do not make their own food , they get their food from other things.
