Performance Evaluation of PEMFC Single Cells under Constant Voltage and Constant Current Conditions

Seon Hyeong Lee, Jae Hong Kim, Jae Heon Kwon, Ryu Bin Kwon, Kwang Hyo Jung, et al.

J. Ocean Eng. Technol.. 2025;39(1):1-8.

Operating conditions significantly affect the durability of polymer electrolyte membrane fuel cells (PEMFC) in marine applications. This study presents experimental results for the performance evaluation of PEMFC single cells under constant voltage and constant current conditions, simulating marine vessel operations. The cells were operated at constant voltages of 0.75 and...

Analytic Study on the Thrust of Two-Dimensional Foil with Aileron in Wave Field

Kyeonguk Heo, Yoon-Rak Choi

J. Ocean Eng. Technol.. 2025;39(1):9-22.

Numerous devices to reduce ship resistance have been suggested. One of them, a propagating hydrofoil in a wave field, can produce thrust and might be used to reduce the resistance of ships. This paper proposes the analytical solution of thrust for a two-dimensional oscillating foil with an aileron in propagating...

Reliability Analysis and Neural-network Modeling of Ship Radar Mast Structure by Adopting Quasi-random Sampling

Chang-Yong Song

J. Ocean Eng. Technol.. 2025;39(1):23-31.

Outfitting structures, such as ship radar masts, require a design that considers the vibration and structural strength performance to ensure safe navigation. Nevertheless, reliability analysis considering design uncertainties is required because of the lack of classification rules for such structure design. This study examined the quasi-random sampling process suitable for...

Wave Transmission Analysis of Timoshenko Beam Junction with Mindlin Plates Connected in the Same Plane

Young-Ho Park

J. Ocean Eng. Technol.. 2025;39(1):32-39.

Energy flow analysis (EFA) models that account for significant shear deformation and the rotatory inertia effects in out-of-plane motion are essential for performing reliable EFA of practical composite structures, such as large ships or offshore platforms. The power coefficients for transmitted and reflected waves caused by incident waves at arbitrary...

Comparison of Residual Stress According to Measurement Methods for Shot-Peened Stainless Steels

Seok-Hwan Ahn

J. Ocean Eng. Technol.. 2025;39(1):40-46.

Residual stress in materials influences the structural and dimensional stability of mechanical components and can lead to damage. In this study, shot peening was performed on stainless steel, a material widely used in ship components and piping, to evaluate the changes in residual stress induced by this process. Residual stress...
