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...

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...

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...

Fuel cell vehicles (FCV) use fuel cells to power the vehicle’s electric motor. Many FCVs use a fuel cell combined with a battery and supercapacitor to efficiently start-up, power, and utilize the best energy source for constant and peak power. In FCVs, the fuel cell uses oxygen from...

Fuel cells with polymer electrolyte membranes are appealing because of their low-temperature operation and relatively simple construction. The polymer electrolyte membrane (PEM) fuel cell consists of two catalyst electrodes (the anode and cathode) separated by polymer electrolyte. Gaseous fuels are fed continuously to the anode (negative electrode), while...

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...

Each component of the fuel cell must be designed properly – otherwise, you run the risk of decreasing fuel cell performance. The bipolar plates are termed “bipolar” because they have flow fields on both sides. This design is very convenient when you have membrane electrode assemblies (MEAs) on both sides. In a fuel cell with a...
