What is the difference between a fuel cell and a battery?
The electrolyte of a battery is generally an acid, a base, an aqueous solution of a salt or other media solution, and the electrolyte of the fuel cell may be a solid or molten salt (e.g., the SOFC electrolyte may be a solid oxide).
The battery does not continuously supply the fuel and has a reversible reaction within the battery, and the reactants in the fuel cell are continuously supplied;
The battery is a secondary battery, and the fuel cell is a battery;
The battery used in the process of charging and discharging cycle, and fuel cell without charge and discharge cycle;
The same thing is: are the chemical energy into electrical energy device, it is called "battery".
