摘要： A fuel cell system comprising a first fuel cell and a second fuel cell is provided. In certain examples, the fuel cell system may be configured to provide an operating variable to monitor fuel cell system performance is disclosed. A fuel cell assembly comprising the fuel cell system and methods of monitoring the fuel cell system are also disclosed. The first fuel is configured to receive a lower amount of fuel than the second fuel cell in a first condition to provide an operating variable indicative of fuel cell stack performance. The operating variable can be a voltage difference between the first fuel cell and the second fuel cell.
