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...

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...

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...

Direct Methanol Fuel Cell Improvements

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...

Using Micro-Transport Phenomena in MEMs Fuel Cells

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...

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...
