(48f) Development of Safety Codes for Deployable Fuel Cell Power Generation Facilities

In Korea, various research activities related to hydrogen and fuel cell technology are being conducted to support the national goal of carbon neutrality by 2050. The adoption of eco-friendly energy sources is being actively considered in both military and civilian sectors, one promising alternative is power generation based on hydrogen fuel cells. In particular, power generation systems based on mobile fuel cells are being developed, and verification applications in military mobile weapon systems and emergency power supply systems are emerging as key areas of focus. These deployable hydrogen fuel cell generators are being developed to achieve high output and long-term continuous operation in military environments, and the development of reasonable safety codes is necessary to ensure stability during operation.

Safety regulations for fuel cell systems in Korea are currently classified under separate product and facility codes, governed by the KGS (Korea Gas Safety) Code. However, there is no established safety code specifically addressing fuel cell power generators that are transportable but remain stationary during operation. These systems differ from conventional mobile or stationary units and require dedicated facility safety codes that reflect their unique operational characteristics.

This study analyzes existing safety codes and regulatory frameworks to support the development of appropriate safety codes for deployable fuel cell power systems designed for dual-use (military and civilian) applications. Current KGS Codes cover hydrogen fueling stations, high-pressure gas charging and storage facilities, and containers for fuel cell vehicles. From these, we reviewed the codes most applicable to deployable systems. Based on this analysis, we propose key considerations and guidance for future safety code development. The ultimate objective is to contribute to the institutionalization of safety regulations tailored to hydrogen fuel cell power systems that are relocatable but used at fixed sites.
