تم في هذا البحث دراسة عملية الإرجاع الكهركيميائي للهدروجين, والعوامل المؤثرة على كمون الإرجاع. حيث درس تأثير تغيير تركيز الحمض على انزياح المنحنيات الفولط - أمبيرومترية المعبرة عن عملية الإرجاع, وبالتالي تأثيره على كل من قيمة كمون الإرجاع لشوارد الهيدرونيوم على المستوى الزئبقي, وسرعة تفاعل الإرجاع الحاصل. وقد تم بعدها إضافة البيريدين كمادة عضوية لحجم محدد من الحمض بتركيز ثابت, وأوجدت العلاقة بين حجم البيريدين المضاف مع كل من كمون إرجاع شوارد الهيدرونيوم على المستوى الزئبقي من جهة , ومع تيار التفاعل الكاتودي(سرعة التفاعل) من جهة أخرى, وأخذت عينة من حمض كلور الماء بتركيز 0.5N وتم إضافة البريدين, وقيس فرق الكمون قبل وبعد الإضافة لملاحظة تأثير هذه الإضافة على فرق كمون تحرير الهيدروجين.
In this research, the electrochemical reduction of hydrogen process and the factors affecting the reduction potential have been studied in this research. The effect of acid concentration on the shifting of the volt-ampero-metric curves that express the reduction process and so its effect on both the reduction potential value of hydronium ions on drop mercury electrode, and the speed value of reduction reaction was studied. Then an amount of pyridine as organic substance was added to a specific volume of acid in a specific concentration to figure out the relationship between the amount of pyridine added and the cathode current of the reaction to find out the effect of added pyridine on the reaction speed and the relationship between the amount of added pyridine and the hydrogen reduction potential. Pyridine was added to amount of acid to study the effect of theaddition on the hydrogen reduction over potential.

Solar Energy and Hydrogen are possible replacement options for fossil fuel, But a major drawback to the full implementation of solar energy, in particular photovoltaic (PV), is the lowering of conversion efficiency of PV cells due to elevated cell t
emperatures while in operation. Also, hydrogen must be produced in gaseous or liquid form before it can be used as fuel; but its‟ present major conversion process produces an abundance of carbon dioxide which is harming the environment through global warming. In search of resolutions to these issues, this research investigated the application of Thermal Management to Photovoltaic (PV) modules in an attempt to reverse the effects of elevated cell temperature. The investigation also examined the effects of the thermally managed PV module to a Electrolyzer (Hydrogen Generator) for the production of hydrogen gas in an environmentally friendly way.
The results of the investigation showed that the cooling system stopped the cell temperature from rising, reversed the negative effects on conversion efficiency, and increased the power output of the module by as much as 33%. The results also showed that the thermally managed PV module when coupled to the hydrogen generator impacted positively with an appreciablely increase of up to 26% in hydrogen gas production.
In this research we studied the mechanism of the reaction the solution ( Malonic acid , Zinc , Water ) by using different methods.
This research focuses on the use of new materials have the ability
to act as an anti-corrosion for the resolution of problems relating to
electrodes analyzers the production of hydrogen. Especially that
most analyzers based on the use of electrodes are expensive.
In this research the electroplating method of chromium was used on
iron ore (steel), it is one of the coating methods for the formation of
a roof cover using chromium (III) chloride salts as a source of
chromium and sulfuric acid as a catalyst.
In this paper, we study the electrochemical deposition process (galvanic coating) of copper (Cu) and zinc (Zn) on stainless iron (path) ores.
