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....
