Full-scale tunnel experiments for fuel cell hydrogen vehicles: Fire-jet and explosions
Résumé
In the framework of the HYTUNNEL-CS European project sponsored by FCH-JU, a set of preliminary
tests were conducted in a real tunnel in France. These tests are devoted to safety of hydrogen-fueled
vehicles having a compressed gas storage and Temperature Pressure Release Device (TPRD). The goal
of the study is to develop recommendations for Regulations, Codes and Standards (RCS) for inherently
safer use of hydrogen vehicles in enclosed transportation systems. Two scenarios were investigated, (a)
jet fire evolution following the activation of TPRD due to conventional fuel car fire, and (b) explosion
of compressed hydrogen tank. The obtained experimental data are systematically compared to existing
engineering correlations. The results will be used for benchmarking studies using CFD codes. The
hydrogen pressure range in these preliminary tests has been lowered down to 20MPa in order to verify
the capability of various large-scale measurement techniques before scaling up to 70 MPa, the subject
of the second experimental campaign
