Investigating the effect of nano catalysts on magnesium-air batteryperformance

Today, due to the limited resources of fossil fuels and environmental pollution, one of the biggestchallenges of the century is the global demand for energy, especially clean and renewable energies,which has forced researchers and scientists to find a solution to this problem [۱-۳]. Fuel cells and airmetalbatteries are efficient systems in producing clean energy. It seems that fuel cells will beconsidered as a solution to the challenges of energy limitation in the future due to the advantages ofenvironmental compatibility, high energy conversion efficiency, fast startup and shutdown. However,fuel cell technologies are currently facing major challenges from difficult hydrogen production,storage, transportation to complex cell design, low stability of electrodes, and high cost of materials [۴-۵]. The structure of fuel cells must be designed to be more efficient. Hydrogen technologies inproduction and storage should lead to material improvements to develop its safety and stability duringoperation. With the proper design of the systems, it is possible to make a connection between theproduction, storage, transportation and use of hydrogen with durability and high efficiency [۶-۷].
