Proton Exchange Membrane Fuel Cell is considered a key device in the hydrogen economy which is a promising energy carrier alternative for the fossil fuels. This paper approaches the problem of membrane conductivity in a PEM fuel cell which influences the major part of the voltage/current polarization curve of the cell. The control of conductivity is essential for stable operation and good performance of the cell. We propose an adaptive 2DOF controller in order to obtain certain control performances for membrane conductivity management. The controller is implemented with 2 PID structures and an adaptation rule which is based on gain-scheduling method. We have determined the controllers’ coefficients and the gain-scheduling change points. Our simulated results show good disturbance rejection while conductivity is maintained at desired level.
