Low Pollution Emission to Purify Fuel Cell Technology Comprehensively: A Review

Abstract

In recent decades, scientists have been urged to build the new energy resources by depleting fossil fuel, high-energy demand and pollution. Being one of the principal alternative power devices, Thanks to the high energy conversion efficiency, the fuel cells have attracted growing attention, simple operation and low pollution emissions. This paper surveys the historical backdrop of the power devices, the energy unit activity, and sorts of energy units, their points of interest, inconveniences and applications.
