摘要：【中文】本发明涉及一种带水路调压功能的燃料电池系统。该系统，包括水箱、高压气源、注气管路、排气管路和排水管路；水箱设置于燃料电池的冷却水水路中，水箱连接有相对独立的注气管路、排气管路、排水管路；注气管路通过注气控制阀与高压气源连接，注气管路、排气管路、排水管路的注气控制阀、排气控制阀和排水控制阀分别连接燃料电池控制系统。且排气管路、排水管路能够合并为排气/水管路；排气管路与燃料电池的进气管路能够直接连接。本发明构简便、容易实现，不受燃料电池操作压力的影响，动态调节燃料电池冷却水路压力的高低，进而控制透水板两侧压差始终位于合理范围内，保护透水板不损坏的同时，还能够正常排水、排气。 【EN】The invention relates to a fuel cell system with a water channel pressure regulating function. The system comprises a water tank, a high-pressure gas source, a gas injection pipeline, a gas exhaust pipeline and a water discharge pipeline; the water tank is arranged in a cooling water waterway of the fuel cell and is connected with a relatively independent gas injection pipeline, an exhaust pipeline and a drainage pipeline; the gas injection pipeline is connected with a high-pressure gas source through a gas injection control valve, and the gas injection control valve, the gas exhaust control valve and the water exhaust control valve of the gas injection pipeline, the gas exhaust pipeline and the water exhaust pipeline are respectively connected with the fuel cell control system. The exhaust pipeline and the drainage pipeline can be combined into an exhaust/water pipeline; the exhaust line can be directly connected to the intake line of the fuel cell. The invention has simple structure and easy realization, is not influenced by the operating pressure of the fuel cell, dynamically adjusts the pressure of the cooling water channel of the fuel cell, further controls the pressure difference at two sides of the water permeable plate to be always in a reasonable range, protects the water permeable plate from being damaged, and can normally drain water and exhaust air.
