TerraLIX Co.,Ltd
TerraLIX aims for the world best technology in air-cooled fuel cell with closed-cathode type. Through the design of our own cell separation plate, we can operate the entire stack stably even under humidity-free conditions (no need for a separate humidifier). The closed-cathode type air-cooled stack has a brand name called HYCUS N series. Based on the air-cooled stack, we are selling a fuel cell module called HYCUS X series.
TerraLIX's fuel cell stacks and modules can be connected in parallel based on their stable output. This allows for the configuration of a power pack of tens of kW class that can be configured with high output density per weight when used as a power supply for large unmanned aerial vehicles and aircraft
The TerraLIX's stack can be configured with portable and emergency generators, with little change in performance for 2,500 hours, and as mentioned, it can be serialized and parallelized for dozens of kW class system configurations
Recently, 1.5 kW portable fuel cells have met European certification, and fuel cells for drones are ready to acquire European certification soon.
