Smedes 6.12 Understanding Hydrogen Fuel Cells

Front

What percentage of hydrogen production is currently through electrolysis?

Back

About 5%.

Front

What is a drawback of steam reforming for hydrogen production?

Back

It releases carbon dioxide.

Front

What is the main environmental benefit of hydrogen fuel cells?

Back

They do not release greenhouse gases.

Front

What is a major source of hydrogen gas for fuel cells?

Back

Separation from water and methane.

Front

How are electrons and protons managed in a hydrogen fuel cell?

Back

Electrons take an alternate path creating an electrical current.

Front

What is electrolysis in the context of hydrogen production?

Back

A process that uses electricity to split water into hydrogen and oxygen.

Front

What is steam reforming?

Back

A method of producing hydrogen by reacting natural gas with steam.

Front

Why is hydrogen considered a clean fuel?

Back

Because its combustion produces only water vapor as a byproduct.

Front

What role do catalysts play in hydrogen production?

Back

They speed up the chemical reactions involved in hydrogen production.

Front

What is the significance of the hydrogen economy?

Back

It aims to reduce reliance on fossil fuels and decrease greenhouse gas emissions.
