Hazard and Operability Study of Proton Exchange Membrane Fuel Cell Hydrogen: Study Case in Hybrid-Electric Train Application

Abstract Proton Exchange Membrane Fuel Cell (PEMFC) is currently being developed as a fuel for trains, especially the type of driven passenger trains. The application of PEMFC on trains requires in-depth study to ensure passenger safety. This is because if the hydrogen tank ruptures, the hydrogen can cause large pressure waves and even explosions if there is an ignition source. The purpose of this study is to determine the hazard opportunities that can occur in PEMFC with the hazard and operability study (HAZOP) analysis method of PEMFC. This method consists of several stages, such as identifying components in PEMFC, determining component deviation, providing risk matrix assessment, and providing recommendations. The HAZOP analysis conducted on the PEM Fuel Cell system showed that 74.167% of the components had low risk, while 25.83% of the components were identified as having medium risk. While components that have a high risk are not found in the system, indicating that the overall condition of the components and system is safe to operate.
