Hydrogen+Cell+Power


 * Hydrogen Fuel Cell Power** William Marshall

Chemical Potential Energy: The energy due to the possibility of a chemical reaction. The type of energy that Hydrogen power starts as.
 * Vocabulary Terms: **
 * Anode:** The electrode through which an electrical current flows into a polarized electrical device. An anode helps create the flow of electrons through a fuel cell.
 * Cathode:** The electrode through which an electrical current flows into a polarized electrical device. A cathode helps create the flow of electrons through a fuel cell.
 * Chemical reaction:** When chemical bonds within molecules are created or broken, also releasing energy. This is what happens to turn hydrogen and oxygen into water and energy.
 * Compound:** Bonded atoms of different types. One of the bi-products of hydrogen power, water, is a compound.
 * Electrode:** A conductor used to establish electrical contact with a nonmetallic part of a circuit.

**Steps of Hydrogen Fuel Cell Power**
 * 1) Hydrogen is fed into the anode of the fuel cell and oxygen is fed into the cathode.
 * 2) The electrons separate from The hydrogen and go through an outside circuit while the rest of the hydrogen goes through the proton exchange membrane.
 * 3) The hydrogen and oxygen meet and form into water.
 * 4) Electrical current is created when the electrons go through the outside circuit.

**Conservation of Energy** The chemical potential energy of hydrogen and oxygen are transformed into electrical energy.

**Advantages of Hydrogen Fuel Cell Power** media type="youtube" key="oy8dzOB-Ykg" height="362" width="450" This is an advantage of a simple fuel cell 5
 * produces no carbon dioxide, meaning that it does not contribute to global warming
 * More efficient than fossil fuel power

**Disadvantages of Hydrogen Fuel Cell Power**
 * there are many steps involved in producing hydrogen
 * there are few places where a hydrogen powered car can be refilled with hydrogen.
