Hydrogen production by PEM water electrolysis – A review

Hydrogen is the most efficient energy carrier. Hydrogen can be obtained from different sources of raw materials including water. Among many hydrogen production methods, eco-friendly and high purity of hydrogen can be obtained by water electrolysis. However, In terms of sustainability and environmental impact, PEM water electrolysis was considered as most promising techniques for high pure efficient hydrogen production from renewable energy sources and emits only oxygen as byproduct without any carbon emissions. Moreover, the produced hydrogen (H2) and oxygen (O2) directly used for fuel cell and industrial applications. However, overall water splitting resulting in only 4% of global industrial hydrogen being…
