Abstract

The invention discloses a fuel cell power system of a long-endurance industrial vehicle. The fuel cell power system comprises a control module, a fuel cell module, a hydrogen storage module used for providing hydrogen for the fuel cell module, an electrical module used for converting output voltage of the fuel cell module and an energy storage module used for storing electric energy generated by the fuel cell module, wherein the electrical module is also used for converting the output voltage of the energy storage module; the hydrogen storage module comprises a hydrogen filling device, a metalhydrogen storage device and a pressure adjusting device, the metal hydrogen storage device is an array device composed of metal hydride hydrogen storage containers, and the metal hydride is an alloyformed by bonding hydrogen and metal under the pressure of 3-6MPa. The hydrogen storage module provided by the invention occupies a small space of an industrial vehicle, can realize the functions of hydrogen storage and industrial vehicle counterweight at the same time, and does not need additional pressurizing equipment during hydrogen filling. In addition, the invention further discloses a long-endurance industrial vehicle.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a long-endurance industrial vehicle and its fuel cell power system. Background technique [0002] Industrial vehicles using fuel cell power systems are cleaner and more environmentally friendly than internal combustion industrial vehicles, have no harmful gas and particle emissions, and are more flexible and stable in operation, with lower noise; compared with lead-acid battery industrial vehicles, the output power is constant, the work performance is better, and the charging is fast. ,higher efficiency. Due to the natural defects of the lead-acid battery itself, the output power and power performance of the forklift powered by the lead-acid battery will drop rapidly with the consumption of electric energy during operation, which not only brings greater operational difficulty to the operator, but also greatly Reduced work efficiency to a certain extent. When driven by fuel cells, indu...
