From present day’s perspective, it has been widely acknowledged that our industrialized
modern world requires new ways to solve the global demand for energy and environmental
associated problems. Conventional sources of electrical energy run by traditional
fuels (like coal, oil etc.) are immensely polluting. Fuel cell technology offers promising and
sustainable options for the future generation energy scenario. The recent commercialization
of fuel cell has been given importance due to its higher efficiency and reduced environmental
hazards. Though the concept of fuel cells is not new, its background is very old. This
article covers the following points: concept of fuel cell, history of fuel cells, fuel cell components,
comparison with batteries, classification of fuel cells, current progress of fuel cell
components, and its present applications status.
Keywords: Fuel cell, galvanic cell, energy, current, membrane, electrocatalyst.
