What Is Fuel Cell Technology?
A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes.
Every fuel cell also has an electrolyte, which carries electrically charged particles from one electrode to the other, and a catalyst, which speeds the reactions at the electrodes.
Hydrogen is the basic fuel, but fuel cells also require oxygen. One great appeal of fuel cells is that they generate electricity with very little pollution—much of the hydrogen and oxygen used in generating electricity ultimately combine to form a harmless byproduct, namely water.вз
Welcome to “City of Materials”
The City is an interactive environment where you can play games, solve puzzles and learn about the materials that you see around you everyday. Here are some tips to help you navigate your way around the City.
Your visit to the City starts in the Park. Click on the map to navigate your way from location to location. You can always see all the locations by clicking on the “Menu and Info” tab at the bottom of your screen or look for a map. All the locations have lots of things to see and do. Look for radios where you can listen to Materials Radio podcasts and pop-ups on everyday items. There are pictures, videos and try it at home experiments. There is even a lab full of equipment at the Griffith CSI lab ready for you to use.
You can explore the City as a guest but if you want to save your progress as you explore the City and solve cases at the Detective Agency then you will need to create a user ID and password. When you first start use the “Register for free!” link to fill out a quick form. Otherwise select “Free Registration” at anytime from the top menu. To learn more, visit The City brought to you by ASM International. Teachers – find classroom instruction materials and great hand-on learning for your students.
Talented and passionate professionals are in high demand in the fuel cell industry. The fuel cell industry is comprised of companies, universities, associations, and government agencies. It is a wide, global network of organizations that are involved at some point along the fuel cell distribution chain. Fuel cells are available for purchase today and the market is steadily growing. Early fuel cell market applications include power for materials handling equipment; backup power for telecommunication towers and data servers; and primary or backup power for retail businesses and commercial buildings. In several applications, fuel cells are becoming cost-competitive with other
power-generation technologies. Although the initial capital cost differential remains high, many companies are finding that fuel cell lifetime costs, including operating costs, are much lower than competing technologies. The many benefits that fuel cells provide – low-to-zero emissions, lower maintenance costs, high reliability, silent operation, faster fueling, and constant, high-quality uninterrupted power – also tip the balance.
