Patent number: 8519717Abstract: Disclosed is a method for detecting ice blocking of a fuel cell stack. In particular, the method includes periodically calculating a minimum cell voltage of a fuel cell stack from cell voltages measured by a cell voltage monitoring system while reactant gases are supplied to the fuel cell stack and then calculating a change in the minimum cell voltage using a currently calculated minimum cell voltage and a previous minimum cell voltage. It is then determined whether the change in the minimum cell voltage is above a predetermined reference value. When the change in the minimum cell voltage is above the reference value, it is determined that the ice blocking has occurred or is occurring in an anode of the fuel cell stack.Type: GrantFiled: June 7, 2010Date of Patent: August 27, 2013Assignee: Hyundai Motor CompanyInventors: Jae Won Jung, Nam Woo Lee, Jae Jun Ko, Sang Uk Kwon, Sun Heum Baek, Sun Soon Park
