2
What are the emissions of Hydrogen Fuel Cells?
Water
New cards
3
What happens to the hydrogen that is inputted into the Hydrogen Fuel Cell?
It is split up into protons and electrons by an electrolyte that only allows protons to pass.
New cards
4
How does the electricity form in the Hydrogen Fuel Cell?
The electrons from the hydrogen takes an alternative path from the Hydrogen Ions, and this flow of electrons creates electricity.
New cards
5
How does the emissions of Hydrogen Fuel Cells form?
The Oxygen that enter the fuel cell break apart, and it attaches to the Hydrogen Ions. This forms water, which is the byproduct.
New cards
6
What is the most common application of Hydrogen Fuel Cells?
In Vehicles
New cards
7
How is the H2 gas for Hydrogen Fuel Cells created?
They use either Steam Reforming or Electrolysis, which require lots of energy
New cards
8
What percent of hydrogen production uses Steam Reforming?
95%
New cards
9
How does Electrolysis compare to Steam Reforming?
Less efficient, but more sustainable
New cards
10
What is Steam Reforming?
Burns natural gas and uses steam to separate H gas from the methane
New cards
11
What are the emissions from Steam Reforming?
CO2
New cards
12
What is Electrolysis?
Electrical current is applied to water, breaking it into O2 and H2
New cards
13
What are the pros and cons of Electrolysis?
Doesn’t emit CO2, although it requires electricity
New cards
14
Pros of Hydrogen as an Energy Carrier
It can be stored in pressurized tanks for later use, and can be used as fuel for vehicles or ammonia for fertilizer
New cards
15
How efficient are Hydrogen Fuel Cells?
80% efficient
New cards
16
Cons of Hydrogen Fuel Cells
Hydrogen Production is based off of non-renewable resources, which releases CO2, Hydrogen tanks in cars also need to larger than for gasoline. There is also no standardized distribution network for Hydrogen.
