I am not able to give you a cost, as there are a number of fuel cell technologies, and it will be difficult to know which ones might ultimately become commercial. So far, fuel cells applications have required large government subsidies.
The "hydrogen car" is still apparently a long ways from becoming a reality- see related links.
Hydrogen Fuel Cell converts the thermal energy released directly into electrical energy.. This fuel cell was used in the Apollo Programe. It also produces water.....
The mitochondria in a cell convert food cells into energy. The cell uses that energy to kickstart necessary reactions.
The fuel for a cell is made up of oxygen and hydrogen. The chemical energy produced by the two is what is converted to serve as fuel for the cell.
The bio fuel cell work on the principle of converting some chemical energy into electrical energy.
The mitochondria in a cell convert fuel particles into usable energy.
The Fuel Cell

chemical energy
fuel cells are the hydrogen fuel cell that operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane.fuel cell is a type of an electro-chemical cell which can convert the fuel energy into electrical energy by reactions of oxidized and fuel particles triggered in the presence of electrolyte
solar energy
A fuel cell (like a battery) converts chemical energy to electrical energy. The main difference being in the fuel cell the energy rich chemicals are continually being resupplied, while in a battery the energy rich chemicals were put in when the battery was initially assembled and cannot readily be replaced or resupplied.
