Question

Draw labelled diagram of H$_2$ - O$_2$ fuel cell. Write two applications of fuel cell.

Hint:

Fuel cells provide an efficient, clean, and environmentally friendly energy source by generating electricity through the reaction of hydrogen and oxygen without producing harmful emissions.

Answer 1

Step 1: Labelled Diagram of H$_2$ - O$_2$ Fuel Cell.
The diagram of a hydrogen-oxygen fuel cell consists of an anode where hydrogen is oxidized and a cathode where oxygen is reduced. The electrolyte between the anode and cathode conducts ions, and the external circuit conducts the electrons generated from the reaction. % Please refer to a labeled diagram of a hydrogen-oxygen fuel cell in your LaTeX editor. Step 2: Applications of Fuel Cell.
- Power generation for vehicles: Fuel cells are used in electric vehicles to provide clean energy. - Backup power sources: Fuel cells are used as backup power sources in remote areas where regular electricity supply is unavailable.
