Stationary fuel cells can produce enough electricity and heat to power an entire house or business -- which can result in significant savings. These fuel cells may even make enough power to sell some of it back to the grid. Fuel cells can also power residences and businesses where no electricity is available. Sometimes it can be extremely expensive for a house not on the grid to have the grid connected to it.    Read more -->

Many factors are contributing to the fuel cell push in the automotive market. The availability of fossil fuels is limited, and due to this, an inevitable price increase will occur. In addition, legislation is becoming stricter about controlling environmental emissions.    Read more -->

In coming years, portable devices—such as laptops, cell phones,video recorders, and others—will need greater amounts of power for longer periods of time. Fuel cells are very scalable and have easy recharging capabilities compared to batteries. Cell phone technology is advancing rapidly, but the limiting factor for the new technology is the power. More power is required to provide consumers with all of the functions in devices they require and want    Read more -->

There are many types of fuel cells that are currently being researched. Different types of fuel cells are differentiated from one another on the basis of their electrolyte and/or fuel that is used with that particular fuel cell type. The common fuel cell types are:

- Polymer Electrolyte Membrane Fuel Cells (PEMFC)
- Alkaline Fuel Cells (AFC)
- Phosphoric Acid Fuel Cells (PAFC)
- Solid Oxide Fuel Cells (SOFC)
- Molten Carbonate Fuel Cells (MCFC)
- Direct Methanol Fuel Cells (DMFC)
- Biological Fuel Cells (BFC)

Polymer Electrolyte Membrane fuel cells (PEMFC – sometimes called proton exchange membrane fuel cells), and DMFCs are very similar except for a few minor differences in the fuel cell construction and the fuel type that is used. Read more -->

Hydrogen is a commonly used fuel for fuel cells, but several other fuels can be used, as well as many types of fuel reforming systems. The cleanest fuel is pure hydrogen because it generates zero emissions. Many fuel cell designs utilize other fuels because of the availability or perceived safety of those fuels. Fuels for fuel cells range from hydrogen to fossil fuels to biofuels. Several types of reformers and chemical conversion methods can convert all of the fuels mentioned previously to hydrogen.    Read more -->

There are many commercially available technologies for storing hydrogen. The most common storage method is the pressurized storage tank, which is available in many sizes and pressure ranges. There are also many other storage methods that are covered in this section.    Read more -->

In order to successfully convert the oil-based infrastructure to a hydrogen one, a radical transformation of the global energy-supply system is required. A large infrastructure to store, distribute, and transport hydrogen would need to be built, and consumers need to be interested in purchasing fuel cell vehicles and other fuel cell products. The total cost of building a hydrogen infrastructure would depend on when and how fast it is built.    Read more -->
