Hello, Secretary? DCF is an indispensable core component in hydrogen fuel cell systems. In 2019, Xinrui Technology took the lead in launching the FC-PEU large-scale integrated solution for hydrogen fuel cell commercial vehicles, which not only greatly improved the integration level, but also achieved "hydrogen refueling with hydrogen and charging without hydrogen". May I ask the company, does it have any new technological breakthroughs and new product launches in hydrogen fuel cells?

In order to meet the needs of hydrogen energy and fuel system customers, it cooperates with the development and service of its fuel cell stack DCF products to realize the function of stack energy control.
