Limiting the increase of global temperature requires electrification of the railway transport, which is relatively a

distinct mode of transport in terms of economy, business and socialization of a country. However, battery

complemented railway transport systems such as fuel cell hybrid railway propulsion systems are constrained by

the high cost of the battery, and suboptimal performance of the fuel cell under varying loads. Optimized selection

of battery can reduce its costs associated with sizing, life and utilization. Similarly, managing the load

distribution between the battery and fuel cell can reduce the load variations concern for fuel cell. In this study,

model-based selective characterization of the battery and fuel cell is done to identify the optimal features and

constraints. Following characterization, the load allocation to battery and fuel cell is determined with the targets

of collaborative utilization of optimal features and mitigation of constraints. Subsequently, considering this load

allocation and results of characterization, conditions are proposed for reliable sizing and optimized selection of

battery. The significance of the proposed conditions in reliable sizing is explored. Based on these conditions,

certain commercially developed batteries are evaluated for optimized selection of battery. The results signify this

study as a foundation for research on the reliable sizing and optimized selection of battery in fuel cell hybrid

railway propulsion systems.
