Kenny Yu EME 1 11/10/08 Power System and Fuel Cells Today, Professor Ericson came to our class to discuss about power systems and fuel cells. He explains why we should convert to from gasoline and diesel to hydrogen fuel cells. The advantages of hydrogen fuel cells are higher efficiency, lower emissions, lower noise, lower maintenance, and decreasing dependence on foreign oil. Hydrogen is an energy carrier rather than an energy source. There are many types of fuel cells such as alkaline, molten carbonate, solid oxide, phosphoric acid, and PEM. To make hydrogen fuel cells, developers split natural gases to get hydrogen. Hydrogen fuel cells are very useful because they can be applied to space, specialty, and terrestrial vehicle applications.

Unformatted text preview: Some challenges about hydrogen fuel cells are the cost, range, durability, power density, and load following. The main concern is the expensive cost of hydrogen fuel cells because it takes a lot of money to make and manufacture it. The only way to solve the expensive cost is to find a way to mass produce hydrogen fuel cells. A fuel cell engine is composed of subsystems: the fuel cell stack, the fuel processing, the thermal management, the water management, the air management, and the power conditioning and energy storage. As engineers, we try to find how hydrogen fuel cells work and the different components of a fuel cell. With the development of the hydrogen fuel cell, fuel is going to be more efficient and environmentally safe....
