  • Patent number: 10818941
    Abstract: A system and device for water evaporation of a fuel cell, and a control method thereof, are disclosed. The system includes a stack provided in a fuel cell vehicle to produce electric power. The system includes an injection member connected to the stack. The injection member retains water generated in the stack, and injects water at high pressure and evaporates injected water particles. The system includes a compressor that supplies high-temperature air to the injection member. Even when the fuel cell vehicle is cold-started, evaporation is enabled through water injection to directly cool air supplied to the stack. Water is evaporated even without a humidifier so that performance of the fuel cell system may be enhanced, while reducing cost.

  • Patent number: 10094811
    Abstract: Disclosed are a hydrogen detection sensor and a method of manufacturing the same. The hydrogen detection sensor is manufactured by using hydrothermal synthesis method to synthesize a molybdenum oxide (MoO3) nanostructure, and irradiating UV light thereon to form an MoO3—Pd nanocomposite comprising the molybdenum oxide nanostructure with palladium (Pd) catalyst particles, and coating the MoO3—Pd nanocomposite on a substrate. As such, a visible color change from the MoO3 before and after exposure to hydrogen may be so obvious that the sensing or sensitivity of hydrogen and the long-term stability may be substantially improved. In addition, the manufacturing process is simple, and the manufacturing costs may be reduced.
