+ Goldfish, Respiratory system: Pets :: Teleosts
  * Goldfish get their oxygen from water. As a fish swims, it gulps up water. Gills have many blood vessels within them. Oxygen moves from the water to the blood as the water flows over the gills. The blood vessels gather and store the oxygen that travels over the gills. At the same time, carbon dioxide moves out of the blood and into the water. Now, the water flows out of the slits beneath the gills. Jishka Homework Help. Jishka Homework Help, 1996-2012.
+ Hydrogen car, The principles of Hydrogen Car, What is the Principle?: Vehicles
  * A fuel cell consists of two electrodes sandwiched around an electrolyte. Oxygen passes over one electrode and hydrogen over the other, generating electricity water and heat. Layers of materials with distinct electrochemical properties are sandwiched together to form a single galvanic cell. At the heart lies a membrane that can only be crossed by charged molecules. Gas-permeable electrodes coated with a catalyst adhere to this membrane, adding a layer on either side. There electrodes are in turn connected to a device that can utilize electricity. Hydrogen gas flows into channels on one face of the cell and migrates through that electrode, while the same occurs with oxygen gas along the opposite electrode.
