Hydrogen fuel cell
Nov 19,2022
This article understands the latest progress of domestic fuel cell cogeneration projects.
As one of the hydrogen energy applications, fuel cell cogeneration/cogeneration can not only provide heat and electricity for buildings, but also recycle waste heat through refrigerators and other equipment to cool and control humidity for buildings, which is conducive to reducing building energy consumption, realizing building energy conservation and turning to low-carbon economy faster.
It can be said that fuel cell cogeneration/cogeneration is one of the indispensable application systems in the future construction field.At this stage, China's fuel cell cogeneration/cogeneration is still in the preliminary stage of research and development demonstration, but many enterprises have started the application demonstration of cogeneration/cogeneration, and have landed the corresponding projects.
Especially since 2021, related enterprise projects have been progressing continuously.
Oriental Boiler & Oriental Hydrogen Energy
In March 2021, China's first self-developed 100 kW-grade hydrogen fuel cell cogeneration system successfully achieved full-load operation in the hydrogen energy demonstration park of Dongfang Boiler Deyang Base. The hydrogen production capacity is 30 Nm3/h, and the hydrogen purity meets the hydrogen standard for fuel cells,The cogeneration energy level reaches 100kW.
In May 2021, the 100 kW-class commercial hydrogen fuel cell CCHP system independently developed by Dongfang Electric (Chengdu) Hydrogen Fuel Cell Technology Co., Ltd. was officially shipped and delivered.

The fuel cell module of the project is provided by Guizhou Hydrogen Energy Efficiency Energy Technology Co., Ltd., and Shun Hua New Energy provides system design, technical support and hydrogen system equipment supply.
The cogeneration equipment adopted by the project is dedicated to fixed power generation scenarios,Operating life up to 40000 hours,The power generation is 100kW, the maximum waste heat recovery power can reach 130kW, and the hydrogen consumption per unit hour is 6.7kg.
Hydrogen energy, as a clean energy that promotes the transformation from traditional fossil energy to green energy, is regarded as a disruptive technology direction of the future energy revolution. Hydrogen fuel cell is the key carrier to realize the conversion of hydrogen energy into electric energy. As the key materials and core components of hydrogen fuel cell, carbon paper and graphite bipolar plate are particularly important.
Hunan EnruiTo meet the needs of the industry, the self-developed series of special thermal equipment such as low-temperature/high-temperature carbonization and graphitization have broken through many key technologies such as intelligent transmission, trace oxygen element control, furnace anti-pollution, efficient heating, intake matching control, exhaust intelligent control, and efficient collection and treatment of by-products. The equipment has been successfully delivered and used in domestic and foreign regions.
