Current Status of Standardization for Fuel Cell Vehicles in Japan -Safety of High Pressurized Hydrogen -

Abstract

This paper will show current status and topics of standardization for fuel cell vehicles especially focused on safety of high pressurized hydrogen such as hydrogen tank on board, fueling connector and fueling protocol. In 2005 JARI S001 was published as the first regulation for hydrogen tank onboard, currently HFCV-gtr (global technical regulation) for hydrogen tank is discussed. Launching hydrogen market in 2015, standardization of fuelling interface becomes urgent issue. Fueling interface consists of fueling connector (hardware) and fueling protocol (software). It succeeded to make a consensus on 70 MPa connector geometry as ISO/DIS 17 268 in 2011. From point of view of safety and performance of fueling, the fueling protocol based on SAE J2601 becomes a hot issue between US, EU and Japan.
