| description | To provide a method of precisely calculating hydrogen gas quantity supplied to on-vehicle cylinder from a difference between hydrogen gas pressure within a measuring cylinder which is measured on a measuring cylinder charging process and a hydrogen gas pressure within the measuring cylinder measured on a hydrogen gas supplying process in consideration that high-pressure hydrogen gas has unstable flow rate and measurement of high-pressure hydrogen gas quantity in terms of flow rate brings about poor reliability.SOLUTION: A hydrogen gas measuring method includes a measuring cylinder preparation process of preparing a measuring cylinder which has a predetermined volume and a predetermined pressure resistance, a measuring cylinder charging process of charging hydrogen gas to the measuring cylinder up to a predetermined pressure and measuring a hydrogen gas pressure within the measuring cylinder after charging and a hydrogen gas supplying process of supplying hydrogen gas to the on-vehicle cylinder from the measuring cylinder after the measuring cylinder charging process and measuring the hydrogen gas pressure within the measuring cylinder after the supply. Therein, a hydrogen gas quantity supplied to the on-vehicle cylinder is calculated from a difference between the hydrogen gas pressure within the measuring cylinder measured on the measuring cylinder charging process and the hydrogen gas pressure within the measuring cylinder measured on the hydrogen gas supplying process.SELECTED DRAWING: Figure 1
【課題】高圧水素ガスは高圧故に流速が不安定で、その量を流速で測ることは精度面で信頼性に欠ける。計量ボンベ充填工程で計測した計量ボンベ内の水素ガス圧と、水素ガス供給工程で計測した計量ボンベ内の水素ガス圧との差分から、車載ボンベに供給した水素ガス量を正確に算出する方法を提供する。【解決手段】水素ガス計量方法は、予め所定の容積と所定の耐圧強度を有する計量ボンベを準備する計量ボンベ準備工程と、計量ボンベに所定の圧力まで水素ガスを充填し、充填後の計量ボンベ内の水素ガス圧を計測する計量ボンベ充填工程と、計量ボンベ充填工程の後に、計量ボンベから車載ボンベに水素ガスを供給し、供給後の計量ボンベ内の水素ガス圧を計測する水素ガス供給工程とを有し、計量ボンベ充填工程で計測した計量ボンベ内の水素ガス圧と、水素ガス供給工程で計測した計量ボンベ内の水素ガス圧との差分から、車載ボンベに供給した水素ガス量を算出する。【選択図】図１ |
