What’s So Good About Hydrogen?

Many automotive manufacturers have chosen fuel cell technology as the long-term solution to replace combustion engines when the oil stops flowing -- but that’s not expected to happen for at least another 15 years (even if we keep using it at our current rate). So why are we...

Become a Renewable Energy Expert

Many years ago, there was a great guy that used to sit next to me at work. We used to laugh a lot when people called themselves “experts.” When it was really true -- we didn’t laugh; however, it often was not true. Our fast-paced culture breeds this mentality because many individuals think that if they do something...

Fuel Cell Reactant Delivery

Small plant components are required to deliver the reactants to the fuel cell with the required conditions. Examples of these components are blowers, compressors, pumps, and humidification systems used to deliver the gases to the fuel cell with the proper temperature, humidity, flow rate and...

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...

Fuel Cell System Design

Fuel cell system designs range from very simple to very complex depending upon the fuel cell application and the system efficiency desired. A fuel cell system can be very efficient with just the fuel cell stack and a few other balance-of-plant components or may require many outside components to optimize...

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...

The Fuel Cell Electrolyte Layer for Low-Temperature Fuel Cells

The electrolyte layer is essential for a fuel cell to work properly. In low-temperature fuel cells, when the fuel in the fuel cell travels to the catalyst layer, the fuel molecule gets broken into protons (H+) and electrons. The electrons travel to the external circuit to power the load, and the hydrogen proton (ions) travel through the electrolyte until it reaches...

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...

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...

Introduction to Fuel Cell Applications

Fuel cells have been researched and developed for use in several applications since the early 1990's. Fuel cells can be used for portable, backup, transportation, and stationary power applications. This article briefly describes some of these uses for fuel cells.

Columbia Chemical Engineering Fuel Cell Car Demonstration and Competition

The first Columbia Chemical Engineering Fuel Cell Car Demonstration and Competition was planned, developed, and executed in order to inspire and educate young people about chemical engineering. This hands-on experience was modelled after the American Institute of Chemical Engineers (AIChE) ChemE Car Competition using the X7 Fuel Cell Car....
