Transcript of "Fuel cell"

  1. 1. Fuel CellsFuel Cells
  2. 2. DefinitionDefinitionElectricity can be converted from the energy of aElectricity can be converted from the energy of achemical reaction. A fuel cell converts thechemical reaction. A fuel cell converts thechemicals hydrogen and oxygen into water,chemicals hydrogen and oxygen into water,while in the process producing electricity.while in the process producing electricity.
  3. 3. How do fuel cells work?How do fuel cells work?The main purpose of a fuel cell is to produce anThe main purpose of a fuel cell is to produce anelectrical current that is then used as a source of energy.electrical current that is then used as a source of energy.Hydrogen and oxygen are used as chemicals to produceHydrogen and oxygen are used as chemicals to producefuel cells. The fuel cell is based on the positive end of anfuel cells. The fuel cell is based on the positive end of anelectric circuit (anode) and negative end of the circuitelectric circuit (anode) and negative end of the circuit(cathode). These ends are separated by an electrolyte,(cathode). These ends are separated by an electrolyte,which is when one metal becomes the anode andwhich is when one metal becomes the anode andcorrodes, while the other acts as the cathode. Thecorrodes, while the other acts as the cathode. Theelectric current is produced with the chemical reaction ofelectric current is produced with the chemical reaction ofthe fuel and the oxidant. The fuel cells get the electronsthe fuel and the oxidant. The fuel cells get the electronsfrom the hydrogen atoms. Then, the electrons movefrom the hydrogen atoms. Then, the electrons movefrom the anode to the cathode. This is what creates thefrom the anode to the cathode. This is what creates theelectric current ends providing us with energy (power).electric current ends providing us with energy (power).
