Role of a Unitized Regenerative Fuel Cell in Remote Area Power Supply: A Review

This manuscript presents a thorough review of unitized regenerative fuel cells (URFCs) and their importance in Remote Area Power Supply (RAPS). In RAPS systems that utilize solar hydrogen power, which typically include photovoltaic modules, proton exchange membrane (PEM) electrolyzer, gas storage, PEM cells, the cost these is currently higher compared to conventional employ diesel generators or batteries. URFCs offer potential solution reduce expenses renewable energy by combining functionalities electrolyzer cell into single unit, thereby eliminating need purchase separate costly units. are particularly well-suited for applications because do not operate simultaneously. mode, function similarly stand-alone electrolyzers. However, performance inferior cells. The presented summarizes past, present, future with details on operating modes URFCs, limitations technical challenges, applications. Solar challenges facing discussed detail.
