Hanwha Ocean-Aero Wins Submarine Fuel Cell System Development Project

Synergy in Export-Oriented Submarine Technology Development

Hanwha Ocean announced on the 20th that it has secured the project for the 'Export-type 3000-ton class KSS-Ⅲ (Next-generation nitrogen-mixed long-life PEMFC module equipped fuel cell system) modification and development' through the weapon system modification and development support project led by Hanwha Aerospace and the Defense Technology Promotion Research Institute.

This project is led by Hanwha Ocean, which has the experience of exporting submarines domestically for the first time and has a dedicated overseas export and specialized research organization. Hanwha Aerospace plans to secure key components of the fuel cell system for export submarines by 2028.

Submarines are core weapon systems of naval forces and require an energy source that can propel them without external air supply for extended underwater operations. For this purpose, the Air-Independent Propulsion System (AIPS) is used.

In particular, the AIP system using fuel cells enables underwater operation for more than two weeks and has advantages such as higher efficiency and lower noise and vibration compared to other air-independent propulsion technologies.

Polymer Electrolyte Membrane Fuel Cells (PEMFC) generate electricity through the chemical reaction of hydrogen and oxygen and consist of an anode, cathode, and polymer electrolyte membrane. They are noted for fast start-up time, low operating temperature, high power density, and environmental friendliness.

Based on its experience in developing fuel cell systems for aviation, civilian ships, and military unmanned underwater vehicles, Hanwha Aerospace plans to develop an independent export-type submarine fuel cell module and secure core technology.

A Hanwha Ocean official stated, "Through this project, we plan to develop a fuel cell system with superior performance compared to advanced competitors and apply it to export-type submarines to further strengthen our competitiveness in the global submarine market."
