This paper proposes the modeling and economic analysis of proton exchange membrane type fuel cells. The fuel cell is an electrochemical device that changes energy from chemical to electrical energy. FC offers clean and effective energy production and it undergoes rigorous growth by numerous manufacturers with different applications. Fuel cells are a promising new technology for the generation of electrical energy. This technology contains hydrogen and oxygen to produce electrical energy through the electrochemical process. A mathematical model of an FC is developed which shows the cathode and anode, output voltage, and economic analysis of the fuel cells. The Simulation results of the fuel cell for a suitable converter Controller are proposed in Matlab 2021b software.

Proton exchange membranes have been synthesized from polyimide (PI) doped with different contents of montmorillonite (MMT) which was obtained by solution casting technique. The enhancement of conductivity was achieved through modification with the MMT. Prepared membranes were systematically characterized in terms of ion exchange capacity, water uptake, methanol uptake, swelling behavior and proton conductivity. Fourier transform infrared spectroscopy and X-ray diffraction measurements were used to confirm the structures of the PI/MMT composite electrolyte membranes. SEM surface morphological images of the composite membranes showed that the MMT nanoclay particles were dispersed uniformly within the membrane what was also reflected in XRD results which indicated a good compatibility of MMT particles with the polymer complex. The TGA spectra showed that the thermal stability of the membrane was reduced by adding MMT into the polymer network. The prepared membrane with 10 wt.% of modified MMT exhibited the highest proton conductivity value of 7.06 × 10-2 S·cm-1 at 70 °C. These results imply the potential application of the PI/MMT composite membranes as improved PEMs for DMFC applications.
