Membrane Comparison Chart - 2024
For PEM fuel cell and electrolyzer applications, a proton exchange membrane is sandwiched between an anode electrode and a cathode electrode. Read more
Membrane Properties and Characterization for Zero-Gap CO2 Electrolyzers
Zero-gap electrolyzers are similar to fuel cells in design because the heart of the electrolyzer consists of two electrodes pressed against a membrane... Read more
What is the Difference Between Carbon Paper and Carbon Cloth Gas Diffusion Layers?
Carbon Paper Gas Diffusion Layers (GDLs) (e.g. Sigracet, Freudenberg, Toray, etc) tend to be thinner and more brittle than Carbon Cloth Gas Diffusion ... Read more
Fuel Cell Electrolyte Layer Modeling
The electrolyte layer is essential for a fuel cell to work properly. In PEM fuel cells (PEMFCs), the fuel travels to the catalyst layer and gets broke... Read more
Processing Alternative Fuels for Fuel Cells
Fuel cells are not limited to pure hydrogen gas as fuel. Each type of fuel cell stack has different fuel tolerances. The lower the operating temperatu... Read more
The Effect of Clamping Pressure on Fuel Cell Performance
There are many steps involved in the manufacturing of a fuel cell stack. One of these steps is the hot pressing of the polymer electrolyte membrane to... Read more
Mathematical Models
Mathematical models are a precise description of a problem, process, or technology in the form of mathematics. These models are built to learn more ab... Read more
Introduction to Fuel Cell Testing
Those who wish to learn more about fuel cells, and even to build their own, may also want to learn how to test those fuel cells. In this post, we will... Read more
