Alternative Liquid Fuel Types for Fuel Cells
Fuel cells usually use compressed hydrogen as the fuel; however, there are many liquid fuels that can be used with fuel cells. Depending upon the system design, liquid fuel types may not be as efficient as pure hydrogen because...
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.
Considerations for Micro and MEMs Fuel Cells

The design elements of a micro or MEMs fuel cell stack are the same as a larger fuel cell stack, except that there should be special considerations for...

History of Fuel Cells

Fuel cells have been known in the scientific community for about 150 years. They began to be explored in the 1800s, and have been extensively researched during the second half of the twentieth and early twenty-first century.  A summary of fuel cell history is shown...

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.

What is a Fuel Cell?

Fuel cells are electrochemical devices that convert chemical energy from the reactants directly into electricity and heat. The device consists of an electrolyte layer in contact with a porous anode and cathode on either side. An illustration of a fuel cell with reactant/product gasses and the ion conduction flow directions through the cell is...
