Dare Japan is committed to the research and development of all solid state batteries and fuel cell stacks. The large size (24V/48V), medium size, and small size (business card size) all solid state batteries exhibited in this exhibition use two technologies: coating and sintering. (1) The main feature of coated batteries is the use of solid oxide electrolyte materials, which can improve manufacturing efficiency and achieve large-scale production. The aim is to develop batteries with widely used characteristics; (2) The characteristic of sintered batteries is the use of full overlap printing technology and integrated sintering technology, aiming to develop larger size and higher capacity all solid state batteries. The two fuel cell stacks independently designed and developed by Del in Japan both use metal bipolar plates: (1) The 30km stack is manufactured using special chemical etching technology for performance verification, combining high-performance membrane electrode assemblies (MA) with the company's independently developed narrow channel bipolar plates; (2) The 10kw stack is designed using stamping and laminated assembly technology, which improves the performance of the stack while also considering batch production and cost control issues.
During the exhibition, personnel from well-known companies such as Toyota, Panasonic, Nissan, Isuzu, Kyocera, and Sattori Electric visited Del Corporation's booth and had in-depth exchanges on various product technologies, exploring the possibility of cooperation. From the establishment of a wholly-owned subsidiary of Dare Auto in Japan in 2018 to the joint development, production, and sales of hydrogen refueling machines with Japan's Longye in 2019, Dare Auto's strategic layout in the hydrogen energy field has received increasing attention from the industry. We believe that through Dare Auto's steady operation and more strong alliances, it will definitely help the development of the company's hydrogen energy industry.
