Question

types of commercial cells​

Answer 1

Answer:

The various commercial cells may be classified mainly into the following three types :

• (a) Primary Cells. Project Report on Primary Cells : Primary Cells are those which the redox reaction occurs only once and the cells becomes dead after some time, and cannot be used again.

• (b) Secondary cells :

(i) Lead storage battery :- This is one of the most common batteries used in the automobile. A 12 V lead storage battery is generally used which consists of 6 cells. Each producing 2.0 V. Each cell consists of a lead anode and a grid of lead packed with lead dioxide as the cathode. These electrodes are arranged alternately, separately by then wooden or fibre glass sheets and suspended in dilute sulphuric acid which acts as the electrode. To increase the current output of each cell, the cathode plates are joined together i.e. the cells are connected in parallel.(C) Project Report on Fuel cells :

• Fuel Cells : As already explained fuel cells are the devices which convert the energy produced during the combustion of fuels directly into electrical energy. One such cell which has been very successful is the hydrogen-oxygen fuel cell. This cell was used as the primary source of electrical energy on the Appolo moon flights. This may be compared with the several tons that would have been required for the engine-generator set.
