discussion of cell

The electrodes used in the cells discussed so far, deteriorate with the passage of current and cannot offer a constant emf indefinitely. However, there was a few cells called standard cells, which can maintain a fairly constant emf over very long perio..

The cells discussed above use a liquid electrolyte, one cathode and an anode. Some of the major disadvantages of these cells are leakage on long term storage, corrosion due to the use of liquid acidic/alkaline solution, short life, low weightage per kg mass of the ..

A layer of neutral hydrogen is formed near the copper rod thus weakening the action of the cell by increasing its internal resistance and also producing a back emf. This is removed by using a depolariser like MnO 2 or CuSO 4 , which oxidizes hydrogen into water. In spite of the small em..

. The management of such non renewable energy sources involves slightly different perspectives from those resources discussed earlier in terms of policy and technology issues. One way of conservation and managing of these resources is to substitute existing technologies so that hydrocarbo..
