Does multi-tank refueling improve hydrogen storage density in fuel cell vehicles?

Refueling in single and multi-tank configuration for fuel cell vehicles was analyzed. Lower gas temperatures during refueling improve hydrogen storage density. Feasible pressure ramp rates ensure safe and efficient refueling under SAEJ2601. Multi-tank refueling enables better space management in fuel cell vehicles.

How safe is a tank based on FMVSS 304?

Tanks in these analyses are designed with a 2.25 safety in reference to FMVSS 304 (49 CFR 571.304).3 The tanks in the test program that generated burst test data used to calibrate the model have an additional amount of composite to account for variations in carbon fiber and manufacturing effectively increasing the safety factor above 2.25.

What is the refueling analysis of a 60 l tank?

The refueling analysis of a 60 L tank is performed to analyze the impact of the increase in tank volume on refueling, as well as to conduct the simulation study of a tank that falls under the refueling criteria of the new SAEJ2601 protocol, i.e., the tank volume must be greater than 49.7 L.

Can NREL hydrogen refueling station model be used for single and multi-tank re fueling?

For this, single and multi-tank refueling is performed with the NREL hydrogen refueling station model at different constant PRRs. The refueling process was assessed based on the temperature, pressure, and SoC attained at the end of the refueling process. Key Findings are summarized below: 1.

What is refueling analysis of type IV FCEV composite tanks?

From the above literature survey, it is evident that refueling is a crucial aspect of hydrogen FCEVs. Therefore, an intensive investigation into the refueling analysis of Type IV FCEV composite tanks is necessary, focusing on parameters such as temperature, pressure, PRR, and refueling station configuration.

Why should fuel cell refueling be regulated under saej2601?

Feasible pressure ramp rates ensure safe and efficient refueling under SAEJ2601. Multi-tank refueling enables better space management in fuel cell vehicles. The escalating global CO 2 emissions, primarily from fossil fuel consumption, underscore the urgent need for sustainable energy sources, particularly in transportation.
