An Introduction to Alkaline Fuel Cells

Alkaline fuel cells (AFCs) was one of the first extensively researched fuel cell types and was used by NASA for the Gemini, Apollo, and Space Shuttle missions. The first alkali electrolyte fuel cell was built by Francis Thomas Bacon (1904–1992) in 1939. He used potassium hydroxide for the electrolyte and...

Calculator for Preparing Methanol-Water Mixture for DMFCs

Direct methanol fuel cells (DMFCs) utilize a mixture of methanol and deionized water (or distilled water) as the fuel for anode side. The most common range for the molarity of the methanol is 0 to 1 Molar and occasionally 0 to 2 Molars (the latter one for advanced users utilizing customized MEAs or CCMs). Our MEAs or CCMs that are manufactured for DMFCs...

The Use of Hydrogen as an Energy Storage System

Many countries around the world have been diligently working towards implementing renewable energy plants for over a decade. According to the International Energy Agency (IEA), renewables in the form of hydropower, bioenergy, wind and solar will account for 18% of primary energy by 2035. Since 2013, more electrical grid capacity was added...

Renewable Energy Rundown: Biomass

This is the fifth and final part in a SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. In this series, we’ve covered a range of renewable power sources. Some, such as geothermal power, have been commonly used for decades. Others, including solar power, have recently risen in popularity due to...

Renewable Energy Rundown: Geothermal Energy

This is the fourth part in a SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Wind, solar, and water are all forces of nature that can provide renewable energy, but did you know we can also draw power from the earth itself? We call this geothermal energy – a power source collected from...

Renewable Energy Rundown: Hydropower

This is the third part in a SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Much like the history of wind power, people have been harnessing the power of water for centuries – a form of energy now known as hydropower. In fact, up until 2019, hydropower was the largest source of total U.S. renewable...

Renewable Energy Rundown: Wind Energy

This is the second part in a SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Harnessing the power of the wind is not a new idea. In fact, humans have been using wind power for hundreds of years. From filling the sails of massive ships to the classic windmills powering grain mills, wind power has...

Renewable Energy Rundown: Solar Energy

This is the first part in a new SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Solar energy has grown in popularity across the country, from massive solar farms to single panels powering residential homes. This is especially true in Texas – which is fifth...

Standards and Requirements for Solar Systems

If you are considering the installation of a solar system (by yourself or by a solar company), there are several codes and regulations that need to be adhered to. These include the National Electrical Code (NEC), local permits, building codes, fire codes, and grounding systems. In addition, every component in a...

Why Fuel Cells Lead The Road to Long-Term Sustainability for Vehicles

Fuel cells have now been under development for several decades. Since I first became interested in fuel cells in the 1990’s, I have seen waves of excitement and investment followed by periods of skepticism and disillusionment. Only a few companies have stayed in the game, with Ballard in Canada and the large automakers such as Toyota being a critical and essential part for...

A Review of Mathematical Modeling of Proton Exchange Membrane and Direct Methanol Fuel Cells

There has been a lot of emphasis on the development of long-lasting, efficient and portable, power sources for further technology improvement in commercial electronics devices, medical diagnostic equipment, mobile communication and military applications. These systems all require...

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...

Building a Micro DMFC Design

This blog post includes a quick fuel cell introduction, parts list and design for a 1 cm x 1 cm (active area) fuel cell. This summary was put together mainly for students interested in fuel cell research. Figure 1 presents a summary of the dimensions and basic characteristics of most MEMs fuel cell stacks in the...

Stationary Fuel Cell Power Applications

Fuel cells can be used for primary power, backup power, or combined heat and power (CHP) for stationary applications. Stationary fuel cells can be sized to power anything from a single-family home to a large business center, which means they make sense for a wide range of markets including retail, data centers, residential, telecommunications, and...

Fuel Cell Buses, Utility Vehicles and Scooters

Fuel cells can be used to power the electric motor of buses, utility vehicles, and electric scooters. The vast majority of these fuel cells use oxygen from the air and compressed hydrogen; therefore, these vehicles only emit water and heat as byproducts. The major reason for developing fuel cell technology for...
