### Characteristics of Fuel Cells in Generating ElectricityThis exercise involves classifying the characteristics of fuel cells used to generate electricity.

Fuel cells are the electrochemical cells that are used to convert chemical energy of a fuel into electrical energy. Every fuel cell has two electrodes i.e. cathode and anode. Fuel cells have electrolytes that transfers ions from one electrode to another. They create very less pollution.(i) Byproduct i.e water is harmless and very less polluting (ii) Hydrogen is available in infinite quantities (iii) No engine sounds (iv) It will be helpful for remote regions as the generation of electricity will be on the site rather than by transmission lines. (v) High Efficiency (i) High Initial Cost (ii) Hydrogen gas is highly flammable, unlike gas it has no smell (iii) Hydrogen gas is to be stored under high pressure due to low energy density. (iv) Refueling station (v) Low service life

Concept explainers

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
