“…Unfortunately, under PEMFC operation conditions, Pt dissolves and breaks up and the carbon support also corrodes leading to the deterioration of the performance of the fuel cell (Kregar et al, 2020). The major degradation mechanisms were identified as dissolution, migration and agglomeration of metal particles and carbon support corrosion that results in a loss in the ECSA which causes overall decrease in the performance of PEMFC (Wang et al, 2021a;Wei et al, 2021b). Several studies have been conducted to investigate the degradation mechanism of Pt/C in PEMFC (Weber et al, 2018;Labata et al, 2021;Fan et al, 2022).…”

Energy is a requisite factor for technological advancement and the economic development of any society. Currently, global energy demand and supply largely rely on fossil fuels. The use of fossil fuels as a source of energy has caused severe environmental pollution and global warming. To salvage the dire situation, research effort is geared toward the utilization of clean, renewable and sustainable energy sources and the hydrogen energy economy is among the most preferred choices. Hydrogen energy economy, which includes hydrogen production, storage and conversion has gained wide consideration as an ecofriendly future energy solution with a fuel cell as its conversion device. Fuel cells, especially, the proton exchange membrane category, present a promising technology that converts hydrogen directly into electricity with great efficiency and no hazardous emissions. Unfortunately, the current generation of proton exchange membrane fuel cells faces some drawbacks that prevent them from large-scale market adoption. These challenges include the high costs and durability concerns of catalyst materials. The main source of high cost in fuel cells is the platinum catalyst used in the electrodes, particularly at the cathode where the sluggish oxygen reduction reaction kinetics require high loading of precious metals. Many research efforts on proton exchange membrane fuel cells are directed to reduce the device cost by reducing or completely replacing the platinum metal loading using alternative low-cost materials with “platinum-like” catalytic behaviour while maintaining high power performance and durability. Consequently, this review attempts to highlight recent research efforts to replace platinum and carbon support with other cost-effective and durable materials in proton exchange membrane fuel cell electrocatalysts. Overview of promising materials such as alloy-based (binary, ternary, quaternary and high-entropy alloys), single atom and metal-free electrocatalysts were discussed, as the research areas are still in their infancy and have many open questions that need to be answered to gain insight into their intrinsic requirements that will inform the recommendation for outlook in selecting them as electrocatalysts for oxygen reduction reaction in proton exchange membrane fuel cell.

“…First of all, in the absence of high potential excursion, the decrease of the cathode ECSA has to be attributed mainly to potential cycling, leading to carbon corrosion, Pt migration and agglomeration, as well as Pt particles dissolution and redeposition, as widely discussed in the literature [ [9][10][11][12][13]84 ]. There is a fairly broad consensus on these mechanisms, although some…”

Paper devices are cutting‐edge platforms for creating miniaturized energy conversion, storage, and sensing devices. In such devices, co‐laminar flow and embedded capillaries not only eliminate membranes and external pumps but also allow widespread application. The fabrication, optimization, and characterization of a microfluidic paper ethanol fuel cell (MPEFC) has been demonstrated in the presented study. The MPEFC uses ethanol and sodium hydroxide as fuel and sulfuric acid as electrolytes. Numerous experiments have been conducted to improve the performance of MPEFC by optimizing various electrode types such as laser‐induced graphene (LIG), Ag nano‐ink/LIG, buckypaper, Ag nano‐ink/buckypaper, and two different 3D printed conductive electrodes. Different electrolyte concentrations (NaOH‐0.25, 0.5, 1 m) have been studied to understand the impact on ion conductivity. It is observed that the developed MPEFC with multiwalled carbon nanotube ‐buckypaper as an optimized electrode, 1 M ethanol with 0.5 m NaOH as anolyte, and 1 m H2SO4 as electrolyte delivered the best performance with a current density of 1756.2 μA cm−2, and power density of 72.62 μW cm−2, at a stable open‐circuit voltage of 235 mV with Gr 1 cellulose microchannel with parallel stacked configuration. This work demonstrates the effective enhancement of the output power with inexpensive individual MPEFC.
