“…Due to the fact that fuel cells' performance is directly proportional to their cell operational temperature, the cell performance is likely to decrease significantly if the cell is operated below or above its required range of operating temperatures. This can sometimes be very challenging as maintaining a constant cell operating temperature often becomes very tedious in the management of the cell [43,49,50]. Mitigation strategies like increasing the relative humidity of the reactants in cell have been proposed in some references, but this equally comes with a cost that often increases the overall cost of the system.…”

“…This can be done in two ways: develop platinum electrodes with lower Pt content (by enhancing the use of Pt from increasing the active Pt sites, thinning the thickness of the active layer and introducing smaller Pt nanoparticles on the carbon support) or with partial or total Pt replacement by other non-precious metals [47]. A valid alternative is represented by palladium which has physical properties similar to Pt but with the great advantage of costing three times less and being 50 times more abundant on Earth [48,49].…”

This review critically evaluates the latest trends in fuel cell development for portable and stationary fuel cell applications and their integration into the automotive industry. Fast start-up, high efficiency, no toxic emissions into the atmosphere and good modularity are the key advantages of fuel cell applications. Despite the merits associated with fuel cells, the high cost of the technology remains a key factor impeding its widespread commercialization. Therefore, this review presents detailed information into the best operating conditions that yield maximum fuel cell performance. The paper recommends future research geared towards robust fuel cell geometry designs, as this determines the cell losses, and material characterization of the various cell components. When this is done properly, it will support a total reduction in the cost of the cell which in effect will reduce the total cost of the system. Despite the strides made by the fuel cell research community, there is a need for public sensitization as some people have reservations regarding the safety of the technology. This hurdle can be overcome if there is a well-documented risk assessment, which also needs to be considered in future research activities.

“…[16][17][18][19] Polyphenyl is a class of rigid chain polymers linked by phenyl groups which is exhibited in Figure 1b. Due to their special physical, chemical, and electrical properties, [20,21] polyphenyl are widely used in batteries, [22] chemical equipment, [23] aerospace, [24] corrosion-resistant materials, [25] and so on. [26] Recently, polyphenyl is a hot research topic, more and more researchers commit to developing its more performance.…”

In this manuscript, a multiple-helical core-shell structure is studied from polyphenyl and boron nitride nanotube (BNNT) through the molecular dynamics simulation. The results exhibited that polyphenyl is constrained in the inside of BNNT and self-coiled to a helical configuration. In these systems, both the van der Waals potential well and the -stacking interaction between the polyphenyl and BNNT play a key role in the formation of helical nanostructures. The final configuration of composites can be influenced by many factors such as the diameter of BNNT, the chain number of polymer, the length of polymer, and the simulation temperature which are investigated in detail. This theory research about polyphenyl and BNNT may supply more theoretical foundation in chemical functionalization and helical polymer synthesis, which can be helpful for fabricating nanoscale devices.

“…Fossil product over the last few years has been the major source of energy generation worldwide [4][5][6][7]. The world today considers it a key contributor to carbon emissions into the atmosphere hence the urgent need to consider an alternative [8][9][10]. Renewable sources are, therefore, perceived as the best replacement for these fossil products [11,12].…”

This investigation explored the performance of PEMFC for varying ambient conditions with the aid of an adaptive neuro-fuzzy inference system. The experimental data obtained from the laboratory were initially trained using both the input and output parameters. The model that was trained was then evaluated using an independent variable. The training and testing of the model were then utilized in the prediction of the cell-characteristic performance. The model exhibited a perfect correlation between the predicted and experimental data, and this stipulates that ANFIS can predict characteristic behavior of fuel cell performance with very high accuracy.
