Question

Which common characteristics makes both batteries and fuel cells practical to use?

Answer 1

Answer: Well they are both portable resources and simple to use with no hectic activity attached to it.

Step-by-step explanation:

Both the batteries and fuel cells are portable resources, which converts chemical energy into electrical energy to provide electricity that powers one or two of our appliances. A battery has self contained chemical power pack which when charge, energy will be stores in it and will produce electricity from the energy it has accumulated inside the battery. Batteries are made up of one or more cells whose chemical reactions create a flow of electrons in a circuit.

while a fuel cell produces the electricity from the fuel in an external fuel tank. This signifies that while a battery may run dead, a fuel cell will produce electricity as long as there is a supply of fuel.

Answer 2

Both the batteries and fuel cells are portable resources, which transforms the chemical energy into electrical energy.

A battery will produce electricity from the energy it has accumulated inside the battery, while a fuel cell produces the electricity from the fuel in an external fuel tank. This signifies that while a battery may run dead, a fuel cell will produce electricity as long as there is a supply of fuel.
