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 broken into protons (H+) and electrons. The electrons travel to the external circuit to power the load, and the hydrogen protons travel through the electrolyte until it reaches the cathode to combine with oxygen to form...
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 the two gas diffusion layers (GDLs). This creates a three-layer laminate membrane electrode assembly (MEA). Other steps involve the machining or etching of the...
Mathematical models are a precise description of a problem, process, or technology in the form of mathematics. These models are built to learn more about a technology, system or method. The models explain why the system or process works the way it does and helps to study the effects and...
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 an essential part of the fuel cell because it causes the gases to spread out to maximize the contact surface area with the catalyst...
The first step in building a fuel cell is to determine the power requirements needed to power the particular device or application. Fuel cells can be used to power anything including phones, laptops, automobiles, buses, houses, businesses and even space shuttles! A single fuel cell can be designed to achieve any current required for a particular application by merely increasing or decreasing the size of the...
The electrolyte layer is essential for a fuel cell to work properly. In low-temperature fuel cells, when the fuel in the fuel cell travels to the catalyst layer, the fuel molecule gets broken into protons (H+) and electrons. The electrons travel to the external circuit to power the load, and the hydrogen proton (ions) travel through the electrolyte until it reaches...
