Gas Diffusion Layers (GDL) are one of the components in different types of fuel cells including, but not limited, to Proton Exchange Membrane and Direct Methanol fuel cells. Gas Diffusion Layers serve to provide conductivity in the cell and control the contact between the reactant gases and the catalyst. This layer also aids in managing the water transport out of the membrane. Another essential function of a GDL is to provide a connection between the membrane electrode assembly and graphite plates in the fuel cell stack.
A numerical model was developed to predict the water concentration, temperature, potential and pressure across a Nafion membrane used in proton exchange membrane (PEM) based fuel cells. The numerical model consists of simultaneously calculating the diffusive flux for water and hydrogen, the proton potential and the pressure and temperature at each node...
Ion-exchanges membranes (IEMs) have many applications beyond fuel cells -- they can also be used to synthesize all types of compounds that are used in various industries. The most popular IEMs consist of polymeric resins with charged functional groups based upon their ion selectivity, they are referred to as anion-exchange (AEM) and...
Anion exchange membranes (AEMS) have been an active area of research for over a decade. AEMS can be used for fuel cells, redox flow batteries, electrolyzers, and even water desalination membranes. The electrolyte layer is the “heart” of electrochemical cells such as fuel cells, batteries, and because it transports ions from...
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...
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...
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...
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...
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...
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...
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...
