The invention discloses a high-power metal plate fuel cell integrated system applied to a forklift, which comprises a metal plate hydrogen fuel cell, a combined frame, a DCDC converter, a system controller, a hydrogen concentration sensor, a deionizer, a radiator and an expansion water tank. A 25 kW metal plate hydrogen fuel cell composed of 84 bipolar plates and matched electric control components such as an oxygen supply system, a hydrogen supply system, a heat dissipation system, an energy storage lithium battery and a DCDC converter are integrated into a complete power supply system, and modular assembly of the whole vehicle is achieved. The rated output power of the system can reach 20 kW, and the operation requirements of large-tonnage forklifts can be met. When the system is used in a small forklift, continuous output can be achieved at a low power point (60% rated power) with higher efficiency, and the service life of the system is prolonged.
