What is the difference between a generator and a fuel cell?
Generators need to provide kinetic energy outside, and fuel cells can rely on their own material to generate electricity; generator is the use of electromagnetic induction to kinetic energy into electricity, fuel cells using chemical reactions to chemical energy into electricity.
With advances in technology, batteries refer to small devices that generate electricity. From here, the battery has two main characteristics: 1. rely on their own to provide electricity; 2. to produce electricity by chemical means.
Look at the definition of the battery: Battery (Battery) refers to contain electrolyte solution and metal electrodes to produce current cups, grooves or other containers or composite containers of space.
