1. Introduction. Proton exchange membrane fuel cells (PEMFCs) are used as environmentally friendly power equipment [] with a high energy density, absence of pollution, low operating temperature, and low noise [2, 3].However, their use is hindered by their high manufacturing cost and short service life.
Membrane-based processes have the remarkable ability to significantly reduce energy consumption compared to traditional methods. For instance, in desalination processes, membranes allow for the efficient removal of salt and impurities from seawater, requiring less energy than conventional thermal methods.
Membrane technology encompasses a wide spectrum of separation methods that rely on semipermeable membranes, enabling the selective separation of various components within fluid mixtures. The versatility of membrane technology is reinforced by its capacity to adapt to a multitude of sectors.
Conventional separation methods like distillation and crystallization have long been recognized for their high energy consumption and adverse environmental impacts. In contrast, membrane technology serves as an exemplar of energy-efficient separation practices.
While the range of their applications is extensive, this section describes some specific uses of these membranes in energy saving via various environmentally friendly applications, including their applications in water treatment, organic solvent recovery, the removal of pharmaceutical and therapeutic contaminants, and gas separation.
The goal is to contribute to environmental objectives by exploring the principles, mechanisms, advantages, and limitations of membrane technology. Noteworthy features include energy efficiency, selectivity, and minimal environmental footprint, distinguishing it from conventional methods.
