英文要約Title : Research and development project for hydrogen utilization technology. Research and development concerning hydrogen station safety infrastructure development. Research and development of an optical hydrogen gas sensor and a hydrogen leak detector. (FY2014-FY2017) FY2016 Annual Report

(1) Research and development of an optical hydrogen gas sensor. (a) Design and fabrication of sensor chip demonstration equipment. As a sensor chip demonstration equipment, a parallel type sensor chip (21× 28×12mm) was designed and fabricated based on the result obtained in the development process. We newly developed a series type sensor chip (30×20×8mm) which realized improvement of energy efficiency, and completed designing and fabricating. We are currently conducting performance evaluation tests of both, and we will complete the evaluation around the beginning of the next fiscal year. (b) Design and fabrication of system demonstration equipment. By integrating the optical elements of the optical switch, the volume ratio of 1/4 (100×100×50mm) to the conventional type was realized. The fabrication of a 1.5GS/s high-speed digitizer has been completed. A system demonstration machine integrating these was fabricated. We are currently implementing the functional evaluation test and complete the evaluation around the beginning of the next fiscal year. (2) Research and development of a hydrogen leak detector. (a) Development of proximity type hydrogen gas leak detector. ・Design of system demonstration equipment. An optimum laser beam splitting ratio capable of detecting the anti-Stokes light most efficiently was found. Based on this result, the optical design of the demonstration equipment was completed. Fabrication will be completed in the first half of the next fiscal year. ・Design of practical probe model. Optical design of probe practical model based on space transmission by articulated mirror was completed. Currently, we are starting to fabricate, and it will be completed in the first half of the next fiscal year. We newly found a fiber transmission method of high-energy pulsed ultraviolet light of mJ order and successfully detected anti-Stokes light by fiber transmission light. (b) Development of remote hydrogen gas leak detector. ・Basic experiment and head part design. Aiming at realization of a compact head part lidar system, DPSS microchip laser and small telescope were used. Based on basic experiments and simulation analysis, a rider optical system configuration that can achieve the target of observation range 8 m, position accuracy 1 m, hydrogen detection limit 1% was devised and the design was completed. Fabrication will be completed around the first half of the next fiscal year. ・Detector and signal processing system design. In order to digitize Raman echo with a 1 ns short pulse light sourc, a high speed digitizer realizing a sample rate of 3GS/s was devised and the design was completed. Fabrication will be completed around the first half of the next fiscal year.
