Hydrogen can be separated from hydrocarbons through the application of heat - a process known as reforming. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. Jump to Other applications - They find uses in a wide variety of settings from residential homes Base load power plants · Solar Hydrogen Fuel Cell Water. Applications. Fuel Cell Today categorises the use of fuel cells into three broad areas: portable power generation, stationary power generation, and power for Fuel and Infrastructure · Portable · Stationary · Transport.

Fuel cells can be used for portable, backup, transportation, and stationary power applications. This article briefly describes some of these uses for fuel cells.
In comparison, secondary rechargeable batteries have battery charger systems that consist of AC chargers that require an outlet to be charged or DC chargers that will recharge your batteries from other batteries.
Rechargeable batteries hydrogen fuel cell applications not practical for certain portable and military electronic applications because they can be heavy and not meet the power requirements.

Some portable fuel cell applications include laptops, cellular phones, power tools, military equipment, battery chargers, unattended sensors, and unmanned aerial and underwater vehicles. A notable difference between rechargeable batteries and fuel cells is that a fuel cell needs a hydrogen fuel cell applications supply of fuel.
Some fuel types that have been used with fuel cells include metal hydrides, methanol, formic acid, ethanol, and of course, hydrogen. For portable fuel cells, methanol and ethanol can be supplied to the fuel cell as fuel or a fuel reformer can also be attached to the fuel cell package.
Fuel cells used for backup power come in many sizes and types and typically use hydrogen as their fuel. Backup fuel cells can be hydrogen fuel cell applications more quickly than other fuel cells because they do not depend on upon the implementation of a hydrogen infrastructure.
Fuel Cell Applications - Fuel Cell Today
Some backup power applications include computer systems, manufacturing facilities, homes, and utility substations. The PEM fuel cell with compressed hydrogen fuel is the most popular fuel cell type used for backup power applications.
There are many fuel options available hydrogen fuel cell applications as compressed hydrogen, liquid hydrogen, propane, natural gas as well as many other fuel types. An electrolyzer system is a good option for backup power applications because it can produce hydrogen on demand.
The electrolyzer can be used with electricity generated by solar panels, a wind source, a nuclear source or electricity generated by the local power company.

hydrogen fuel cell applications Many fuel cell demonstration vehicles have been created for each of these vehicle types.
Automotive manufacturers are interested in fuel cell technology because it is a "next-generation" technology that could have fuel reproduced from local sources and low or zero emissions. Fuel cell vehicles usually use compressed hydrogen as the fuel type, although several manufacturers have also demonstrated a fuel cell vehicle with methanol.
Automotive fuel cells can have one or more of the following: The difference between buses and automobiles are the power requirements, space availability, operating regimen, and refueling sites. Buses require more power than automobiles and get more wear due to hydrogen fuel cell applications stops and starts.
Large quantities of hydrogen can also be stored on-board buses easily because of the available area of a bus.
Fuel cell buses have an advantage over diesel buses because they have zero emissions. This is critical in heavily populated and polluted cities. Many bus manufacturers began demonstrating their first fuel cell buses in the early s.
The space between the two electrodes is filled with a concentrated solution of KOH or NaOH which serves as an electrolyte. H2 gas and O2 gas are bubbled into the electrolyte through the porous carbon electrodes.
