摘要： Proposed are a system for preheating a fuel cell for a fuel cell vehicle and a method controlling the system. An information collector collects start pattern information regarding a start pattern of a driver including start dates, positions, and times of a fuel cell vehicle when the vehicle is started. A controller classifies a start date in the start pattern information of the driver as a weekday group or a weekend group, classifies a start position in which the start of the vehicle is concentrated as a position group, classifies a start time in which the start of the vehicle is concentrated as a time group, deduces a predicted next start time based on each group when the vehicle is stopped, and controls a temperature increase of a fuel cell based on the predicted next start time when the fuel cell is stopped.

摘要： A fuel cell system that raises temperature of fuel cells by supplying heated air to the fuel cells during starting up period. The fuel cell system includes a plurality of fuel cells, a fuel supply path connected parallelly to the fuel cells to provide fuel thereto, an air supply path connected serially to the fuel cells to provide air thereto, a heat exchanger arranged in the fuel supply path to heat air or fuel, an air heat exchanger arranged in the air supply path to heat air; and a connection path connecting a position of the air supply path upstream to the air heat exchanger with a position of the fuel supply path upstream to the heat exchanger. A first control valve is arranged in the air supply path for controlling the air flowing into to the air heat exchanger. A second control valve arranged in the connection path for controlling the air flowing into the heat exchanger. The fuel cell system controls opening degrees of the first and second control valves during the start-up period of the fuel cell system to supply heated air to the fuel cells through both the air supply path and the fuel supply path.

摘要： In a fuel cell system, a first rubber seal is interposed between a top part of a first seal bead portion that is formed to protrude toward a first separator main body, and a membrane electrode assembly member. A method of low temperature starting of the fuel cell system includes: a warm-up step of warming up a fuel cell stack by introducing an oxygen containing gas discharged from a compressor, into a case interior space in a state in which a temperature of the oxygen containing gas is raised by causing the oxygen containing gas to flow through a pressure loss member; and an electrical power generating step of initiating generation of electrical power after completion of the warm-up step.
