Title3: Research and Development for International Standardization for Hydrogen Quality Control (FY2013-FY2017) FY2016 Annual Report

Subtheme1: Research and Development for Appropriate, Reasonable and Simple Method for Hydrogen Quality Control (HySUT)
(1) Development of Hydrogen Quality Control Guideline
We revised the hydrogen quality control guideline to clarify the content and frequency of routine hydrogen analysis.

(2) Development of Hydrogen Sampling System and Hydrogen Sampling Method
We manufactured high/low pressure sampling system for hydrogen gas supplied from the refueling nozzle in HRSs (Hydrogen Refueling Station) .
We sampled hydrogen gas in over 50 HRSs in order to analyze the characteristics of ISO14687-2 using this system.

(3) Development of a Simple Analytical Instrument
We achieved analysis of impurity components in hydrogen (H2O, N2, O2, CO, THC, CO2, NH3, H2S, HCHO, HCOOH, He) using TOF-MS(Time of Flight Mass Spectroscopy) method with H2O monitor and concentrator installed.
Also, we achieved Subtheme1 objectives for a short-time analysis using TOF-MS method.

(4) Development of Filters in HRSs for Particulates in Hydrogen
Effect of fluid flow on particulate behavior which was initially attached on a filter was investigated by a numerical simulation. In this study, the fluid and particulate were assumed to be the hydrogen and glass beads, respectively. When the Reynolds number was 44, the particulate was not released from the filter. On the other hand, when the Reynolds number was 175, the particulate was released from the filter. Hence, the particulate behavior was simulated under the hydrogen flow.

(5) Verification Tests in HRSs
We conducted verification tests for hydrogen samplings from refueling nozzle in over 80 commercial HRSs. Also, we confirmed the validity of TOF-MS method.
We sampled high and low pressure hydrogen gases to analyze them using a conventional method and TOF-MS method respectively as a TOF-MS evaluation of HRSs site.


Sub-theme 2: Research and development of an inexpensive and simple method for Hydrogen Quality Control allowing further cost reduction (SCAS)
(1) Development of hydrogen gas sampling and analysis method using solid medium samplers
A sampling kit with non-liquid, solid medium samplers was manufactured and tests were conducted at three hydrogen stations. With the use of this sampling kit, the analysis cost and time are expected to be reduced.

(2) Development of the on-site gas sampling and analysis method
Improvement in analysis instruments and gas sensors were made for the on-site gas analysis, along with studies in methods to remove hydrogen thus concentrating the impurities to be analyzed.

Sub-theme 3: International standardization in the fuel quality for fuel cell vehicles (JARI)
JARI has organized the Fuel Quality WG to discuss the issues on the following international standards for hydrogen fuel quality. JARI took a convenership of ISO/TC197/WG28 and managed the progress of ISO19880-8 "Hydrogen Quality Control". WG28 finished CD comments and finalize the draft of DIS. It is expected to be published by the end of year 2017.
As for ISO14687 (the Hydrogen Fuel Quality) started the discussion on the WD and its comments, then the ISO/CD 14687 was officially registered. It is expected to be published by the end of year 2018.
Further, JARI has performed the evaluation test of the FC performance on several impurities such as organic hydrides, CO and formaldehyde. Those data were reflected in the hydrogen quality specification discussion in ISO.
