It is much easier to control the hydrogen and oxygen during direct combustion than during their reaction in a fuel cell.
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
A fuel cell is a electrochemical device that converts the chemical energy of fuels such as hydrogen and natural gas, and oxidants like air and oxygen into electricity.Fuel Cell FunctionalityFuel cells generate electricity from a simple electrochemical reaction in which an oxidizer, typically oxygen from air, and a fuel, typically hydrogen, combine to form a product, which is water for the typical fuel cell. Oxygen (air) continuously passes over the cathode and hydrogen passes over the anode to generate electricity, by-product heat and water. The fuel cell itself has no moving parts - making it a quiet and reliable source of power.The electrolyte that separates the anode and cathode is an ion-conducting material. At the anode, hydrogen and its electrons are separated so that the hydrogen ions (protons) pass through the electrolyte while the electrons pass through an external electrical circuit as a Direct Current (DC) that can power useful devices. The hydrogen ions combine with the oxygen at the cathode and are recombined with the electrons to form water. The reactions are shown below.Anode Reaction: 2H2 => 4H+ + 4e-Cathode Reaction: O2 + 4H+ + 4e- => 2H2OOverall Cell Reaction: 2H2 + O2 => 2H2OIndividual fuel cells can then be combined into a fuel cell "stack." The number of fuel cells in the stack determines the total voltage, and the surface area of each cell determines the total current. Multiplying the voltage by the current will yield the total electrical power generated.Power (Watts) = Voltage (Volts) X Current (Amps)

A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
Potato power does not technically count as a fuel cell because of its electrochemical processes and solid fuel source.

Generator that utilizes Hydrogen is called "Fuel Cell" it is an Electrochemical Energy Conversion Device that converts the chemicals Hydrogen and Oxygen into Water and during this process the Electricity is generated.
Water is the benefit of a hydrogen fuel cell ;)
A biological fuel cell is another term for a microbial fuel cell, a bio-electrochemical system which drives a current by mimicking bacterial interactions found in nature.
The fuel cell hydrogen is one of the two gasses, that are created by the seperations of a water molecule H2O. A water molecule consists of H - hydrogen, and O - oxygen. A fuel cell hydrogen is the gas created by the separation of a water molecule with the help of a fuel cell.
There are no commercially available hydrogen fueled cars.
No. Hydrogen fuel cell is not a title. You would only capitalize hydrogen if it was at the beginning of a sentence, as I did with this one. Otherwise, you would say 'hydrogen fuel cell'.

No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.
