Fuel Cell Primer

Fuel cells produce electricity from reactants such as oxygen and hydrogen -- although other fuels besides hydrogen can be used. The electrochemical reaction produces water and heat as byproducts. Fuel cells are much more efficient than the internal combustion engine because they provide more...

Fuel Cell Stack Temperature in Mid-to-High Temperature Fuel Cells

There is an acute need for the development of long-lasting, efficient and portable power sources for further technology improvement in automobiles, commercial electronics devices, military and stationary applications. These systems all require the power source to be energy-efficient, and able to operate for long periods of time without...

Using Micro-Transport Phenomena in MEMs Fuel Cells

A lot of work has been devoted to the development of long-lasting, efficient and portable, power sources for further technology improvements in commercial electronics devices, medical diagnostic equipment, mobile communication and military applications. These systems all require...

Renewable Energy Systems in the Future: Part 2

Electricity for residential and business use can be produced using a combination of wind, solar, and hydrogen fuel cells. There also needs to be cooperation between corporations, utility companies, and individuals to successfully transition to a renewable energy economy. Corporations will have to manufacture...

Renewable Energy Systems in the Future: Part 1

Despite the recent negative publicity surrounding fossil fuels, crude oil, and natural gas have been beneficial for the growth of the modern world. It has allowed us to have life after dark, transport goods all over the world, and enabled technology to advance. However, the use of fossil fuels has also resulted in...

Introduction to Electrolyzers

Electrolyzers use electricity to break water into hydrogen and oxygen. The electrolysis of water occurs through an electrochemical reaction that does not require external components or moving parts. It is very reliable and can produce ultra-pure hydrogen (> 99.999%) in a non-polluting manner when...

Water Management For PEM Fuel Cells

One of the greatest challenges associated with PEMFCs is the water balance in the fuel cell stack. As the chemical reaction occurs in each cell, water is generated. Depending upon the load and the operating conditions, there is a tendency for the fuel cells to both flood and dry-out. The water content in the...

Considerations for Fuel Cell Design
When you first consider your fuel cell stack design, you will need to calculate several main factors to make sure you are getting the power that is required.  This post will provide you with an overview of the initial considerations for fuel cell design in room-temperature fuel cells.
Characteristics and Safety of Hydrogen

Hydrogen has many unusual characteristics compared with other elements. Some of these interesting and unusual characteristics include...Table 1 compares relevant properties of hydrogen, methane, methanol, ethanol, propane, and gasoline—all of which can be used as fuel for fuel cells.
