GAC Group has once again made significant progress in the exploration of hydrogen energy technology, and its self-developed 140kW hydrogen fuel cell stack has officially rolled off the production line, marking a key step in the research and development of core hydrogen energy technologies.
The research and development of this hydrogen fuel cell stack lasted more than a year, and the GAC team successfully overcame a number of technical problems, including the design and preparation of integrated single cell and integrated box seal technical solutions. Through these technological innovations, stacks have achieved three major breakthroughs: high integration, high energy ratio and high safety.
In terms of integration, GAC has adopted a new integrated design, which reduces the volume of the stack by 25% and the weight by 0%. This highly integrated and modular design not only improves the space utilization and load capacity of the vehicle, but also provides more possibilities for the adaptation of multiple vehicle platforms. An image showing an integrated box-sealed fuel cell stack shows the practical application of this technology.
In terms of energy ratio, GAC has increased the power density of the stack to 7kW/L by adopting ultra-thin metal plates and high-performance membrane electrode technology, which is in a leading position in the industry. The ultra-thin metal plates not only improve the power output, but also reduce the material cost and volume weight; The high-performance MEA ensures the efficient operation of the electrochemical reaction, improving the overall performance and energy conversion efficiency. A picture of relevant leading experts visiting the exhibits of ultra-thin metal plates further proves the advanced nature of this technology.
In terms of safety, GAC has equipped the stack with multiple protection systems, including active and passive hydrogen exhaust systems, enhanced electrical isolation design, and anti-vibration and impact structures. Together, these designs create an all-encompassing safety net that ensures safety in a wide range of conditions of use. The stack also meets a -67°C cryogenic start-up and IP0 rating, and has passed accelerated aging tests to verify its reliability and durability under extreme conditions.
GAC Group has been deploying in the field of hydrogen energy since 9, and after years of innovation and practice, it has mastered the dual technical route of hydrogen fuel cell and hydrogen engine. In the field of passenger cars, GAC has launched the first hydrogen fuel cell SUV in China, the AION LX Fuel Cell, and has carried out demonstration operation in the Guangdong-Hong Kong-Macao Greater Bay Area. At the same time, GAC has also independently developed a hydrogen engine and installed it on the flagship GAC Trumpchi E0, becoming the world's first passenger car equipped with a hydrogen-electric hybrid system. A picture of GAC's hydrogen fuel cell passenger car AION LX Fuel Cell in demonstration operation in the Guangdong-Hong Kong-Macao Greater Bay Area shows the practical application effect of this technology.
In the field of commercial vehicles, GAC has also demonstrated strong technical strength. Its stack technology can be extended to hydrogen heavy-duty trucks and megawatt-level power generation systems, providing key technical support for the green transportation ecology. GAC Hino's release of Guangzhou's first hydrogen fuel cell commercial vehicle and the strategic cooperation agreement signed with Yuanshang Co., Ltd. for 1000 hydrogen energy logistics vehicles are testaments to GAC's innovative application capabilities in the field of commercial vehicles. A picture showing a hydrogen fuel cell commercial vehicle highlights GAC's achievements in promoting the commercial application of hydrogen energy technology.
These achievements of GAC Group have not only laid a solid foundation for its own development in the field of hydrogen energy, but also provided strong support for the green transformation of the entire industry.
