1. Hydrogen fuel cell field

Hydrogen fuel cells are technologies that produce heat simultaneously by converting chemical energy of hydrogen and oxygen directly
into electrical energy by electrochemical reactions, and are new and renewable energy devices with 70 to 80% efficiency.
In particular, it is a renewable energy device that can replace internal combustion engines of cars,
batteries for drones, and power sources for households.
