In the second part a multiple cell stack was constructed and integrated with photovoltaic<br />

array to evaluate cell performance with the optimum working condition findings that was<br />

found in the first part.<br />

The thesis contains six chapters. Following with this introduction, a literature<br />

review on the <strong>production</strong> of <strong>hydrogen</strong> and also the PEM electrolyzer (<strong>from</strong> material<br />

development to thermodynamic analyses studies to the investigation of integration of PEMs<br />

with <strong>solar</strong> <strong>cells</strong>) is presented in details in Chapter II. In Chapter III, the specifications of the<br />

materials and also the procedures used to construct PEM electrolyzer and the integration<br />

with the <strong>solar</strong> panels are explained. In addition, the test methods to analyze the performance<br />

of the PEM electrolyzer <strong>using</strong> the bench scale power supply and also the <strong>solar</strong> panels are<br />

presented in this chapter. In Chapter four, the characteristic performance evaluation plots,<br />

such as the voltage versus the current density or the power density versus the current<br />

density and mass balance across the cell, are presented for the bench scale power supply<br />

operated and also the <strong>solar</strong> panels integrated electrolyzers. The parameters affecting their<br />

performances are discussed by considering the <strong>hydrogen</strong> <strong>production</strong> rates, the cell<br />

efficiency, the construction materials and also the cell construction way. Finally, the<br />

conclusions obtained in this study are listed in Chapter five which follows by some<br />

recommendations in same chapter.<br />
