The disclosure generally describes a method for venting pressurized hydrogen gas from a device for simulating a refueling operation for a fuel cell electric vehicle (FCEV).

Method of venting a pressurized hydrogen gas from a hydrogen station testing device

Heat is transferred from a first portion of liquid hydrogen to a flow of a heat transfer fluid at a first heat exchanger through heat exchange with a heat transfer fluid to produce a flow of vaporized hydrogen and a warmed flow of heat transfer fluid. The flow of vaporized hydrogen is combined with a second portion of liquid hydrogen in amounts designed to produce a combined flow with a desired temperature, the combined flow being used to fill one or more buffer vessels. Heat is also transferred at a second heat exchanger from a stream of pressurized hydrogen from the at least one buffer vessel to the cooled flow of heat transfer fluid to produce a cooled flow of pressurized hydrogen that is used to fill tanks of fuel cell electric vehicles.
