Honda Fuel Cell System Technology

Transcript

00:00We have been focusing on hydrogen energy for over 30 years through research and development

00:09in fuel cell technologies and FCEVs with the aim of realizing carbon neutrality.

00:18This led us to develop the new fuel cell system in collaboration with General Motors.

00:24The new system is more than twice as durable as the conventional type.

00:30The low temperature resistance performance has also been greatly improved.

00:42The system was evolved by a new cell structure.

00:47The cell is formed by three plates, two bipolar plates and a unitized electrode assembly.

00:56Simple structure has been realized by integrating flow channels on bipolar plates.

01:02Furthermore, the configuration of cooling flow channels in the bipolar plate consisting

01:08of two plates allows each cell to cool efficiently and improves durability.

01:15This has been realized through extremely advanced welding technology.

01:20Ensuring stability in welding strength between plates of 0.1 mm thickness has successfully

01:26achieved cooling individual cells.

01:37Hydrogen and airflow inside the stack on both sides of the unitized electrode assembly and

01:42the heat generated during power generation is removed by the cooling water inside the

01:48bipolar plates.

01:51Power is generated within each cell by reacting hydrogen with oxygen in the air.

01:57Only water is emitted.

02:00But power generation efficiency drops in the area around the cell if the humidity is too

02:07high or too low.

02:09The optimization of humidity control with an electric thermal valve and a high efficiency

02:15humidifier improves the stability of power generation performance.

02:20This also prevents cell degradation and improves durability.

02:25New fuel cell system evolved through a variety of technologies.

02:36The new fuel cell system will be installed in CRV-FCEV.

02:51CRV-FCEV with the new fuel cell system that achieves clean and powerful driving realizes

02:58carbon neutrality.
