Abstract
In order to improve the accuracy of hydrogen consumption measurement using a Coriolis flowmeter, we conducted chassis dynamometer tests using a fuel cell vehicle. In this report, we used high-pressure hydrogen that is more than 1MPa and a hydrogen flow meter with a pressure adjustment mechanism to improve measurement accuracy. As a result, even in the transient driving cycles such as WLTC and JE05, where past tests showed variations, test results by Coriolis flowmeter were obtained that closely matched the measured values using the gravimetric method, which was determined from the difference in the weight of the gas cylinder before and after the test.
