MICROBIAL FUEL CELL-REVIEW

CIVIL ENGINEERING

Energy is the most fundamental requirement of today’s era. Energy is consumed very rapidly. The energy requirements are very increasing. Our population, abundant energy resources and industrial diversity make our self proficient enough in producing and consuming energy. This will definitely leads in contributing to the national economy. It is the fact that initially there is a cost issue with every new technology but gradually developing mind we can cope up with it. The need for optimization in cost and efficiency can create systems which are cost effective, non- hazardous in nature, commercially available, clean fuel, compete with regular ongoing systems, inherently safe in handling, having renewable power and sustainable to nature. We envision a future where industries can fulfil the growing demands in an environmentally sustainable way. Hydrogen fuel cells have the real potential to be the future technology in terms of applicability. This technology has the solution to the problem of increasing requirements in an environmentally viable option. This review article presents the working operation of Hydrogen Fuel Cell, Classification of fuel cell in a comparable way, applications, new developments, future technologies and economic growth. Fuel cell is very much similar to the electrochemical cell or an ordinary dry cell. There are basically three components in each and every fuel cell. They are cathode, anode and electrolyte. They are connected with the electrical circuit. This construction has no rotating parts in its design. Hence, they are pretty simple and efficient in design. The classification is based on the type of electrolyte used.
