Hydrogen Fuel Cells Flashcard

Front

What is a hydrogen fuel cell?

Back

A hydrogen fuel cell is an electrochemical device that converts the chemical energy of hydrogen and oxygen into electricity, with water and heat as byproducts.

Front

List three potential applications of hydrogen fuel cells.

Back

1. Transportation (cars, buses, trucks) 2. Stationary power (homes, businesses) 3. Portable devices (laptops, phones)

Front

What is one disadvantage of hydrogen fuel cells?

Back

Low production cost is often cited as a disadvantage, as hydrogen fuel cells can be expensive to produce compared to other energy sources.

Front

How can the public support the growth of fuel cell technology?

Back

The public can support fuel cell technology by investing in companies, advocating for clean energy policies, and educating themselves and others about fuel cells.

Front

True or False: Hydrogen fuel cells have been in use since the early 1800s.

Back

True

Front

What is one advantage of hydrogen fuel cells?

Back

Hydrogen fuel cells are a clean energy source, producing only water and heat as byproducts.

Front

What is a potential solution for hydrogen storage?

Back

Metal hydrides are a potential solution for storing hydrogen.

Front

Define 'clean energy source'.

Back

A clean energy source is one that produces energy without harmful emissions, contributing to a reduction in pollution and environmental impact.

Front

What is the role of oxygen in a hydrogen fuel cell?

Back

Oxygen acts as the oxidizing agent in a hydrogen fuel cell, reacting with hydrogen to produce electricity.

Front

What are the byproducts of a hydrogen fuel cell?

Back

The byproducts of a hydrogen fuel cell are water and heat.
