Hydrogen fuel cells Flashcards
1
Q
advantages of hydrogen fuel cells
A
- clean technology (water waste product)
- high efficiency (no combustion products)
- quiet
- simple construction
- high power density
2
Q
disadvantages of hydrogen fuel cells
A
- expensive
- storage is difficult (flammable+explosive)
- cells decompose + need to be replaced
- net energy loss (energy required to produce H is more than what is produced in its use)
3
Q
what are the components of hydrogen fuel cells
A
- protein permeable membrane
- cell coated in platinum
- holes to allow H2 and O2(air) to enter
4
Q
why is the cell coated in platinum
A
platinum is a catalyst and also inert
5
Q
what is the purpose of the proton permeable membrane
A
acts like a salt bridge
6
