“…Mapping modifications of such magnetic fields can be employed as non-invasive diagnosis methods to detect and isolate faults in PEMFC themselves. Changes in current density distribution inside PEM and overall performances can be monitored using magneto-tomography data [ 429 , 430 , 431 , 432 , 433 , 434 , 435 , 436 ]. Some authors also investigated the effect of these self-induced magnetic fields on the corrosion of the metal bipolar plates in PEMFCs.…”

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.

Polymer electrolyte fuel cells (PEFCs) play a crucial role in approaching net-zero commitments due to their high-power density, rapid refuelling, and environmentally friendly operation. However, ensuring stable performance and durability relies on subtle water balance. Existing water management control strategies, including humidification, drainage, and cold starts, primarily depend on indirect feedback or calibration through the output voltage. The direct, real-time measurement of the water content inside a PEFC remains challenging, hindering the implementation of an efficient feedback control strategy for water management. To address this issue, synchronous measurement of neutron imaging and electrochemical impedance spectroscopy (EIS) is carried out at various water contents for the first time to the best of our knowledge. Machine learning is used to establish a nonlinear correlation between these two characterisation techniques. This enables the development of a more cost-effective and easily accessible real-time water content estimation technique suitable for high-power applications inferred from a universal EIS characterisation tool rather than relying solely on the limited availability of neutron imaging. This approach facilitates the optimisation and advancement of PEFCs.
