“…The Proton Exchange Membrane Fuel Cell (PEMFC) utilizes pure hydrogen as fuel, with only water being produced as a result of the electrochemical reaction. 1 This makes it both pollution-free and carbon emission-free, providing a significant advantage in terms of improving the marine environment and reducing energy consumption and emissions. 2 When discussing the marine environment, it is important to consider unique characteristics that differ significantly from those of the terrestrial environment.…”

In the maritime setting, Proton Exchange Membrane Fuel Cells (PEMFCs) are subjected to salt spray, posing a risk of contaminating internal components and leading to irreversible degradation in the performance of the PEMFCs. Thus, it is crucial to assess the impact of sodium chloride contamination on PEMFC operation. To address challenges related to prolonged cycle times, high costs, and intricate sample preparation in sodium chloride contamination experiments for PEMFCs, this Article replicates the marine atmospheric conditions using a standard salt spray experimental chamber. The liquid nitrogen fracture method is employed for cost-effective and efficient preparation of experimental samples. The meteorological environment with varying salt content in the salt spray is achieved through precise control of sodium chloride concentration. The Article systematically presents the salt spray experimental method for the membrane electrode assembly (MEA) of PEMFCs. A dedicated salt spray experimental rig was constructed to validate this method for the MEA of PEMFCs. The results indicate that the salt spray experimental method for the MEA of PEMFCs can effectively explore internal component contamination and is well-suited for analyzing the physicochemical effects of NaCl on MEA components, along with their microscopic characterization under salt spray conditions.

“…Solid oxide fuel cell (SOFC) is one of the highly efficient energy conversion devices that converts chemical energy directly into electrical energy through electrochemical reactions. [1,2] It has renewable energy conversion devices with significant potential due to their low emission, high efficiency, and easy fuel availability. [3] SOFCs are mainly divided into two structures: tubular SOFCs and planar SOFCs.…”

Flow condition in gas channels determines the distribution and diffusion of reactants, governing electrochemical reactions in the solid oxide fuel cell (SOFC). It is found that the magnitude and direction of fluid velocity change with the geometric position in the channel, which leads to larger secondary flow velocity components and enhances mass transfer between fluids. Laser Doppler velocimetry experiment is conducted to verify the accuracy of numerical results of fluid flow in chaotic flow channels. Herein, a 3D numerical model with coupled multiphysics fields is built to evaluate fluid flow in channels and SOFC performance. The distribution characteristics of reactants in chaotic flow channel and the characteristics of temperature distribution, current density and power density in SOFCs caused by structures of straight and chaotic flow channels are analyzed and discussed. Compared with conventional straight flow channel SOFCs, the average current density of SOFC with chaotic flow channel is improved and the power density is increased by 9.7%. The reactant homogeneity in the electrode is also improved, which reduces the concentration polarization loss of SOFC.

“…A fuel cell system can deliver the required power during stable operation, while the performance of the fuel cell system can degrade markedly when the demanded power changes dramatically [7]. Concurrently, an output power that is too high or too low in the fuel cell can cause a decrease in efficiency and damage the fuel cell [8].…”
