Ion filter roof structure of fuel cell for vehicle

摘要

An ion filter roof structure of a fuel cell for a vehicle is provided and includes a controller that is connected to a heater, a pump, a 4-way valve, and a radiator disposed within a fuel cell for a vehicle. In addition, a thermal management system of the ion filter roof structure includes an ion filter and a fuel cell stack connected to the controller to form an ion filter roof. Based on this structure, during high output, a cooling performance of the vehicle is improved, durability of the ion filter is improved, and a pump operation is decreased to improve fuel efficiency.
