Advantages of a Hydrogen Fuel Cell
1. It can be a renewable source of electricity if the hydrogen comes from a renewable resource. See the advantages of hydrogen as a fuel.
2. It does not produce pollution or contribute to global warming because the only product is water.

A hydrogen fuel cell is made from an anode and a cathode with an electrolyte contained between them.
The fuel cell generates electricity. It is not the same as an electrolysis cell which needs to be supplied with electricity.
The electrolyte in an alkali fuel cell is potassium hydroxide (KOH).

Disadvantages of a Hydrogen Fuel Cell
1. Each fuel cell only makes a small voltage.
A large number of fuel cells must be wired together to produce a large voltage or current. This is expensive.
2. Hydrogen is explosive and difficult to store.

The anode is a platinum catalyst. Hydrogen is supplied to the anode and it reacts with hydroxide ions from the electrolyte to make water. This is an oxidation reaction in which electrons are lost from hydrogen. The electrons leave the anode and travel through the external circuit which is using the electricity that is supplied by the fuel cell.

Fuel Cells Essay

simple device is referring to a fuel cell. The book definition of a fuel cell is a “device that generates electricity by a chemical reaction”(#1). The purpose of using a fuel cell is to create an electrical current that can be directed outside the cell to do various types of work. Some examples of work that a fuel cell may be used for may include; powering an electric motor or lighting up a light bulb. In order for a fuel cell to complete these tasks, each fuel cell needs two electrodes known as an…

Hydrogen Fuel Cell Essay

fossil fuels such as coal, oil and natural gas. Normally electricity is converted through a two step process. Fuels are burnt converting chemical energy to heat. The heat is then transformed into electricity by generating steam to turn turbines. This is a highly inefficient method which requires a development of another more efficient method of producing electricity. In addition, fossil fuels are non – renewable energy resources. They are limited and will eventually run out. Fossil fuel cells produce…
