arise during fuel cell operation. The difference between actual cell voltage at a given current density (current per unit active electrode area) and the reversible cell voltage for the reaction is termed overvoltage (overpotential when referring to a single electrode). Prominent sources of overvoltage in a fuel cell are 1. Mixed potential at electrodes arising due to unavoidable parasitic

A paper published in 2009 in Energy Policy (in the context of this fast moving field admittedly fairly dated) comparing battery electric, hydrogen fuel cell and fuel cell hybrid vehicles found that the drivetrain costs of full FCEVs is around 50% higher than battery electric vehicles, which were in turn 12 times the cost of a conventional ICE drivetrain.

interfaces, and (B, bottom) a fuel cell showing the continu- ous supply of reactants (hydrogen at the anode and oxygen at the cathode) and redox reactions in the cell.
Fuel cells can generate power almost indefinitely, as long as they have fuel to use. The reactions that produce electricity happen at the electrodes. Every fuel cell has two electrodes, one positive, called the anode, and one negative, called the cathode.
Fuel cell technology is twice as efficient as combustion in turning carbon fuel to energy. Hydrogen, the simplest chemical element (one proton and one electron), is plentiful and exceptionally clean as a fuel.

However, while a battery makes electricity from the energy it has stored inside the battery, a fuel cell makes its electricity from fuel in an external fuel tank (learn how a fuel cell works). This means that while a battery may run dead, a fuel cell will make electricity as long as fuel is supplied. For hydrogen fuel cells, hydrogen is the fuel and it’s stored in a tank connected to the fuel

Difference Between Cell and Battery The cell and battery both store the chemical energy and then transforms the stored chemical energy into an electrical energy. One of the major difference between the cell and the battery is that the cell is the single unit, whereas the battery is the group of cells.
In a fuel cell vehicle, the hydrogen fuel is combined with oxygen. While the combustion in a hydrogen- or gasoline-powered engine is converted into mechanical energy, in a fuel cell vehicle, the chemical energy from the hydrogen and oxygen is converted into electrical energy. Of course, this is a very simplified version of what’s actually going on under the hood. If you’re not quite sure about
What is the Difference Between a Battery and a Fuel Cell?
Battery-powered electric cars and hydrogen fuel cell vehicles have both seen advances in their development, and one or both of these technologies may represent the future of “green” automobiles.
The fuel cell represents the fourth category of batteries. Fuel cells are similar to batteries except for the fact that that all active materials are not an integral part of the device (as in a battery). In fuel cells, active materials are fed into batteries from an outside source. The fuel cell differs from a battery in that it possesses the capability to produce electrical energy as long as

Most devices designed to use dry-cell batteries can operate between 1.0 and 1.5 V. Could this cell be used to make a battery that could replace a dry-cell battery? Why or why not. Why or why not. Suppose sulfuric acid is added to the half-cell with the lead electrode and some PbSO 4 ( s ) forms.
Specifically, battery-electric vehicles and hydrogen fuel-cell vehicles have been developed as so-called zero-emission vehicles (ZEV) to help reduce overall fossil fuel consumption and GHG emissions occurring at the vehicle.
Currently, the fuel-cell vehicle and the battery electric vehicle (BEV) are the only potential ZEV replacements for the internal combustion engine, however, no studies have directly compared the two technologies in terms of performance and cost when considering the most recent advances in battery and fuel-cell technology.
