Fuel Cell Basics
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...
Batteries store and produce energy as needed. In PV systems, they capture surplus energy generated by your PV system to allow you to store energy for use later in the day. Like technologies such as fuel cells, a battery converts chemical energy to electrical energy. Rechargeable batteries also...
This post will help you to determine how to size a photovoltaic (PV) system. By calculating the power, current, and voltage output required, the size and the number of photovoltaic panels can be estimated. Also, the voltage and current requirements will determine how the solar panels in...
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 review some basic terms, and introduce low-cost testing equipment and more sophisticated testing setups. First, however, an understanding of the fuel cell and electrical basics will...
Photovoltaic (PV) panels are comprised of individual cells known as solar cells. Each solar cell generates a small amount of electricity. When you connect many solar cells together, a solar panel is created that creates a substantial amount of electricity. PV systems vary in...
Understanding the flow of heat in a fuel cell is important to design and build a fuel cell properly. The energy that flows into and out of each process unit in the fuel cell needs to be accounted for to determine areas of excess heat and the overall energy requirements. There are several methods that...
