| چکیده مقاله |
| Water separator is one of the main parts of a cascaded fuel cell stack. In separators, water droplets are separated from the wet gas. To control the water level of the separator, two lower and upper limits are considered. Improper control of the separator water level can cause the active surface of the fuel cell to become flooded which leads to fuel and oxidant starvation. As a result, the production capacity of the fuel cell is reduced. Therefore, it is very important to control the water level of the separator. In this paper, an experimental investigation is done for water level control system of a cascaded PEM fuel cell stack. The investigation is based on air bubble detection sensor.Water separator is one of the main parts of a cascaded fuel cell stack. In separators, water droplets are separated from the wet gas.
