Development of All-in-one Smart Hydrogen Station

Article of Honda R&D Technical Review Vol.29 No.2

Summary

An all-in-one smart hydrogen station has been developed, using Honda’s original high differential pressure water electrolysis technology. The key components are packaged to be the size of a ten-foot container, reducing footprint and simplifying installation work. In addition, an interface was created to be easily understandable for those having no hydrogen refueling experience. In terms of performance, the pure water production method was revised to reduce water consumption to less than one tenth of the previous method. In addition, high-pressure water discharge technology was developed to increase the durability of the hydrogen production system. Furthermore, in order to expand the installable area to include semi-cold regions, heater functionality was added, preventing function loss from freezing. With these changes, smart hydrogen stations are being introduced by municipalities and private parties around Japan as an effective approach for achieving a hydrogen society and for promoting popularization of fuel cell vehicles.
