A device that converts energy of combustion of fuels like hydrogen and methane, directly into electrical energy is known as

Fuel cells convert the energy from hydrogen directly into electrical energy through what process?

Hydrogen power plants operate on the principle of converting what energy stored in hydrogen fuel into electrical energy?

Engines help vehicles move by burning different types of fuels. Gasoline is a common fuel that is made of molecules containing hydrogen and carbon atoms. A spark plug is used to burn a mixture of fuel and air in the engine. This process causes the fuel-air mixture to expand and move a piston up and down, eventually resulting in the motion of different parts of the car.​Drag the descriptions into the correct boxes to complete the diagram showing the flow of energy in an engine.​

There are many sources of energy available.Methanol fuel cells provide a portable energy source. The process can be represented by the overall equation CH3OH(aq) + 32O2(g) → CO2(g) + 2H2O(g).Deduce the half-cell equations occurring at each electrode during discharge.
