“…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.

“…Based on the experimental data in [4], a method to calculate the current intensity distribution the magnetic field at four points is presented in this study. The experiment was performed using a 5-cell PEMFC stack with a constant current of 15 A for 1 h and an unhumidified hydrogen and air supply.…”

“…According to our research, the number of measurement points can be reduced and evaluated by inserting them in an air-cooled fuel cell [3]. We have also previously demonstrated that the system can be used for control as it enables real-time identification of faults such as flooding or dry-out by considering the measurements from at least two magnetic sensors, but only the current distribution at the time of the fault [4].…”

The current intensity distribution of a fuel cell is an important factor that determines its performance. A contactless method that does not affect the fuel cell and can accurately and quickly assess internal cell conditions is required to measure the current distribution. Therefore, this study proposes a simplified method to measure current distribution based on four magnetic field measurements. The proposed method demonstrates that the purge control performed in flooding during constant-current operation results in non-uniform current distribution, despite effective voltage recovery. This study shows that the method is useful to eliminate the non-uniformity of current distribution for improving long-term operation of fuel cells.
