Fuel Cell Basics
Small plant components are required to deliver the reactants to the fuel cell with the required conditions. Examples of these components are blowers, compressors, pumps, and humidification systems used to deliver the gases to the fuel cell with the proper temperature, humidity, flow rate and...
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...
After the membrane electrode assembly (MEA) has been fabricated, it must be integrated into a fuel cell stack. The stack has multiple jobs, including evenly distributing fuel and oxidant to the cells, collecting the current to power the desired devices, and evenly distributing or discarding heat and...
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 temperature of the stack, the stricter the requirements for pure fuel. For fuels other than pure hydrogen, an external fuel processing system may...
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 alternative method of producing hydrogen via a chemical reaction. These reactions involve chemical hydrides, water, and alcohols. The chemical reactions are not reversible, and the byproducts must be discarded. Hydrogen fuel can also...
Fuel cells usually use compressed hydrogen as the fuel, but there are many other types of fuels that can be used. The type of fuel used depends upon the fuel cell application. Fuels are often in their final form before entering the fuel cell; however, certain fuel cell types can be processed on the inside of the fuel cell. Alternative fuel types are...
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...
This post will help you to determine the best location for a photovoltaic (PV) system. After you have sized your PV system based upon the calculated the power requirements, you will have to select a location that has maximum sun exposure and limited shading throughout the year. PV arrays can be...
When you receive your energy bill each month, you may not understand exactly how the total amount has been calculated. Every device or appliance in your household contributes to the total sum of the bill. To figure out which appliances and devices are using the most energy, you can estimate 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...
