  • Patent number: 10985388
    Abstract: A method of estimating hydrogen crossover loss of a fuel cell system including a stack for producing power through a reaction of hydrogen serving as fuel and air serving as an oxidizer includes driving the fuel cell system; estimating a hydrogen crossover rate right after a channel of an anode is purged; determining whether a cell voltage of a fuel cell is normal; and comparing the estimated hydrogen crossover rate with a predetermined reference value based on a result of the determining of whether the cell voltage of the fuel cell is normal to determine whether a pinhole or leakage occurs. Accordingly, whether a pinhole or leakage occurs in the fuel cell system may be more effectively sensed.

  • Patent number: 10957923
    Abstract: A hydrogen fuel cell vehicle system and method inhibit formation of black ice on road surfaces at low temperatures as a result of exhaust water by treating the exhaust water prior to discharge with a deicing or antifreeze substance to lower the freezing point of the water. A metering device may meter a deicing or antifreeze substance, such as sodium chloride, calcium chloride, urea, or the like to be dissolved in the exhaust water that is produced during the production of energy. The vehicle may include a bypass valve that selectively bypasses the water treatment system when ambient conditions are not conducive to ice formation. The bypass valve is operated to direct exhaust flow to a condenser and water treatment system when ambient conditions are favorable to ice formation, with the deicing or antifreeze substance metered based on current or predicted ambient or road surface conditions.
