Abstract: In this paper, the internal structure and category of fuel cell were firstly described as well as the electricity-generating system. In addition, the current situation of the application of fuel cell in the electricity-generating industry was discussed including its prospects. In the end, the assumption of the application of fuel cell in the electricity-generating industry was explored.

Abstract: Electrochemical studies on nickel hydroxide have shown that three reduction reactions take place simultaneously at the cathode to reduce nitrate to nitrite, nitrite to ammonium ion and nitrate to ammonium ion. All the three reactions produce hydroxyl ion which raise pH to a level favorable to precipitate Ni(OH)2. Current density, which regulates flow of OH- supply, has prominent effect on the process and products. It determines whether α- or β-Ni(OH)2 would be precipitated and has a direct relationship with size and structure of the product and also with the associated water molecules. Replacement of Ti anode with consumable Ni sheet remarkably improves current efficiency (production rate) and decreases power consumption.
