“…Several factors affect the performance of PEM fuel cells, such as the preparation method of the catalysts layer [ 408 , 409 ], the design of catalyst ink [ 410 ], the catalyst loading [ 411 ], the size of the catalyst [ 412 ], the flow field design to supply the fuels [ 413 ], the type of fuels [ 395 ], the presence of contaminations in the fuels [ 414 ], the choice of materials [ 401 , 415 ], the operating conditions [ 395 , 401 , 416 ] and so on. Additional parameters that can affect the performance of a PEMFC are magnetic fields.…”

The relationship between magnetism and catalysis has been an important topic since the mid-20th century. At present time, the scientific community is well aware that a full comprehension of this relationship is required to face modern challenges, such as the need for clean energy technology. The successful use of (para-)magnetic materials has already been corroborated in catalytic processes, such as hydrogenation, Fenton reaction and ammonia synthesis. These catalysts typically contain transition metals from the first to the third row and are affected by the presence of an external magnetic field. Nowadays, it appears that the most promising approach to reach the goal of a more sustainable future is via ferromagnetic conducting catalysts containing open-shell metals (i.e., Fe, Co and Ni) with extra stabilization coming from the presence of an external magnetic field. However, understanding how intrinsic and extrinsic magnetic features are related to catalysis is still a complex task, especially when catalytic performances are improved by these magnetic phenomena. In the present review, we introduce the relationship between magnetism and catalysis and outline its importance in the production of clean energy, by describing the representative case of 3d metal Pt-based alloys, which are extensively investigated and exploited in PEM fuel cells.

“…The serpentine shape generally generates a higher differential pressure than that of the interdigitated parallel shape. [46][47][48][49] Furthermore, because a liquid fuel (e. g., methanol or glucose) has significantly higher density and viscosity than those of a gas fuel (e. g., hydrogen or air), the diffusion is difficult to occur in the rib region of the flow field. [11] The channel region is dominant in the diffusion and reaction.…”

A nonenzymatic glucose fuel cell directly oxidizes glucose to gluconic acid as a Pt‐based abiotic catalyst in a proton exchange membrane environment and has various advantages (e. g., biocompatibility, chemical stability, high ionic conductivity). We report the permeability of a less hydrophobic diffusion layer for three flow‐field designs (serpentine, interdigitated, and parallel). In all cases, as the channel width of the flow path increases, the power density increases and the Ohmic resistance decreases. The serpentine shape (channel and rib widths: 1.5 and 0.5 mm, respectively) exhibits remarkable maximum power and current densities (cell voltage: 60 mV) of 103.4 μW cm−2 and 1,273 μA cm−2 compared to those of the parallel (46.5 μW cm−2 at 683 μA cm−2) and interdigitated (74.0 μW cm−2 at 878 μA cm−2) shapes, respectively. Furthermore, permeability and performance analyses according to the single‐cell temperature, glucose concentration, and flow rate changes provide various perspectives on glucose fuel cells.

Proton exchange membrane fuel cell (PEMFC) is a portable and clean power generation device. The structural arrangement of the flow field has a significant influence on the delivery efficiency of PEMFC. In this article, a new bionic flow channel is designed based on the inspiration of a spider shape. The branch channel width and branch corner are studied as the focus, and its simulation is carried out by the method of computational fluid dynamics (CFD). The results show that when channel width/rib width and corner of the branch are 1.5 and 130 o , respectively, it is the best numerical combination and the cell comprehensive performance is excellent. The final model using this numerical combination is compared with the traditional flow channel model to verify the advancement of this scheme.
