In order to facilitate an understanding of the experimental setup, the contents described in Reference [18] are briefly described as follows. The PEMFC humidifies all air and hydrogen, before they are supplied to the unit cells, in order to prevent the drying effect of hot air.…”

Abstract:We propose a wave-like design on the surface of cathode channels (wave form cathode channels) to improve oxidant delivery to gas diffusion layers (GDLs). We performed experiments using proton-exchange membrane fuel cells (PEMFCs) combined with wave form surface design on cathodes. We varied the factors of the distance between wave-bumps (the adhesive distance, AD), and the size of the wave-bumps (the expansion ratio, ER). The ADs are three, four, and five times the size of the half-circle bump's radius, and the ERs are two-thirds, one-half, and one-third of the channel's height. We evaluated the performances of the fuel cells, and compared the current-voltage (I-V) relations. For comparison, we prepared PEMFCs with conventional flat-surfaced oxygen channels. Our aim in this work is to identify fuel cell operation by modifying the surface design of channels, and ultimately to find the optimal design of cathode channels that will maximize fuel cell performance.

“…Although the PEMFCs have such good features, there are some drawbacks that need to be solved. For instance, high cost of membrane, 4 water management, [5][6][7] expensive catalyst, 8 and so on. Both experimental and numerical studies are carried out to solve these problems and to explore the potential of the PEMFCs.…”

This study represents a comprehensive investigation of the performance of Artificial Hummingbird Algorithm for parameter estimation for Polymer Electrolyte Membrane Fuel Cell. With this purpose, four commercial fuel cell systems which were widely preferred in the literature such as NedStack PS6 (Case-I), 250 W fuel cell stack (Case-II), Horizon 500 W (Case-III), and BCS 500 W (Case-IV) were chosen. In order to compare the performance of this algorithm, seven well-known optimization techniques including Artificial Bee Colony, Salp Swarm Optimization, Particle Swarm Optimization, Gray Wolf Optimization, Genetic Algorithm, Harris Hawks Optimization, and Whale Optimization Algorithm were used. The sum of the squared errors, computational speed, and statistical measurements were calculated for the performance comparison. In this context, the best SSE values were found as 2.06556, 5.25017, 0.02477, 0.01170 for Case-I, Case-II, Case-III, and Case-IV, respectively. The best standard deviation value was found as 1 e−6 for the Case-III. Based on the obtained results, the Artificial Hummingbird Algorithm established itself as a competitive optimization technique for parameter estimation study of PEMFC in terms of computational speed and robustness.

“…Nowadays, with the aggravation of environmental pollution and the depletion of fossil energy, there is an urgent need for a new type of power plant. The proton exchange membrane fuel cell (PEMFC), as the fourth-generation generator set and the generator set instead of the internal combustion engine, has become the focus of attention. − Moreover, the PEMFC has high energy conversion efficiency and stability, which makes it applicable to various fields. − However, the reason why the commercialization of the PEMFC is hindered is that it has a high cost of manufacture and an excessive pressure drop. Furthermore, the types of flow field plates have a significant impact on the pressure drop and cost of the PEMFC. − In addition, intelligent manufacturing as the current cutting-edge production mode has not been applied to the manufacture of flow field plates. , Therefore, this article lowers the pressure drop and cost of the PEMFC by a novel flow field plate design.…”

The flow field plate is a crucial factor affecting the pressure drop and cost of a proton exchange membrane fuel cell (PEMFC). In order to lower the pressure drop and cost of the PEMFC, a novel design method for the flow field plate structure was proposed. One of the originalities was the fact that intelligent manufacturing technology was applied to the design of the flow field plate, and the other one was the analysis of the pressure drop and cost of the PEMFC through experiments. First, the relationship between the flow field plate and the pressure drop was analyzed by using the finite volume method. Second, a PEMFC with a novel flow field plate was designed and manufactured, which was using intelligent manufacturing technology. Third, three types of flow field plates were tested by using a self-developed PEMFC test stand. Finally, three types of flow field plates were compared and analyzed, which included the cost of hydrogen, the cost of manufacture, and the pressure drop difference. When the relative humidity was 25% and the operating temperature was 333 K, the average difference between the pressure drop of the novel flow field plate and the serpentine flow field plate was 0.16%.
