An Introduction to Ion Exchange Membranes and Salt Splitting
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... Read more
Kinetics of Ion Exchange Materials Pt. 2
The primary mode of ion transport is diffusion, which is process of the movement of atoms, ions, molecules, or energy from a region of high concentra... Read more
A One-Dimensional Heat, Mass and Charge Transfer Model for a Polymer Electrolyte Fuel Cell Stack
Abstract
A one-dimensional heat, mass and charge transfer model was developed for a polymer electrolyte fuel cell stack to predict the temperatures, ... Read more
A Review of Mathematical Modeling of Proton Exchange Membrane and Direct Methanol Fuel Cells
Introduction
There has been a lot of emphasis on the development of long-lasting, efficient and portable, power sources for further technology improv... 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
Chemical Hydrides
Fuel cells often use compressed hydrogen as the fuel; however, many other hydrogen sources can be used with fuel cells. Chemical hydride storage is an... 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
Gas Diffusion Layer: Characteristics and Modeling
The gas diffusion layer (GDL) in a fuel cell can consist of a single layer or a double layer (gas diffusion layer and a microporous layer). The GDL is... Read more
Membrane Electrode Assembly (MEA) Characterization
Selecting the appropriate technique to properly characterize the fuel cell is extremely important because it helps the user to understand why the fuel... Read more
Explanation of the Thermodynamics Behind Fuel Cell & Electrolyzer Design
Thermodynamics is the study of energy changing from one form to another. Many predictions can be made using thermodynamic equations, and these are ess... Read more
Direct Methanol Fuel Cell Improvements
