SYSTEM AND METHOD FOR MANAGING FLOW AND PRESSURE CROSSCOUPLING

The present disclosure is generally directed to systems and methods in a vehicle or powertrain system that include flowing an air flow through an air compressor and an air cooler into a fuel cell stack, flowing the air flow from the fuel cell stack to an environment through a back pressure valve, one or more sensors are used to measure the pressure or temperature in the first air flow or the second air flow, and a controller controls the flow of the first air flow, the flow of the second air flow, and the opening of the back pressure valve. 本公开总体上涉及车辆或动力系统中的系统和方法，所述方法包括使空气流通过空气压缩机和空气冷却器流动到燃料电池堆中，使空气流通过背压阀从燃料电池堆流出到环境，一个或多个传感器用于测量第一空气流或第二空气流中的压力或温度，以及控制器控制第一空气流的流动、第二空气流的流动和背压阀的打开。
