A new dynamic model is developed in this paper to connect PEM Fuel Cell (PEMFC) to a Z-source inverter (ZSI). This
model is used to analyse the behaviour of a fuel cell by providing a polarization curve. A controller is designed based on
an interpolation to spot parameters of PEM Fuel Cell such as temperature (or anode and cathode pressure). A current
feedback is gained to regulate the output voltage through determination of physical parameters. The ZSI is used in the
proposed model to generate AC power. In this research, to compensate the voltage drop of fuel cell the capacitor voltage
of the Z-network is controlled using the state space averaging method to stabilize the AC output voltage of the ZSI.
Simulation and experimental results verify the validity of the proposed controlling model
