Which of the following is an example of simple fuel cell?

Which of the following is an example of simple fuel cell?

  • A. Lead storage battery
  • B. Leclanche cell
  • C. \( H_{2} O_{2} \)
  • D. All of the above

Step-by-step solution

A simple fuel cell converts chemical energy from a fuel (like hydrogen) and an oxidant (like oxygen) directly into electricity. The hydrogen-oxygen fuel cell is a classic example. Lead storage battery is a rechargeable battery, not a fuel cell. Leclanche cell is a primary dry cell. Therefore, only option C is correct.

  • Primary battery is a battery:
  • As a lead storage battery is charged.
  • In continuously supplied energy which can be withdrawn indefinately until outside supply of reactant is maintained. These cells are more eff
  • a fuel cell, combustion of hydrogen occurs to:
  • Assertion A large dry cell has higher emf. Reason The emf of a dry cell is independent of its size.
