Research summary
يهدف البحث إلى دراسة تأثير توزيع الماء على أداء خلية الوقود الهيدروجينية ذات الغشاء البروتوني (PEMFC)، وعلاقة سماكة الغشاء وتأثير تغير سماكته تبعًا لكمية الماء الموجودة ضمن الغشاء. كما يهدف البحث إلى دراسة تأثير الرطوبة على فعالية الغشاء البروتوني من خلال معامل الانتشار ومعامل التدفق الكهربائي التناضحي. يتضمن البحث دراسة الرطوبة على أداء الخلية عند درجة حرارة ثابتة وتأثيرها على مدخلات التفاعل. هناك العديد من البارامترات المترابطة فيما بينها وذات التأثير المتبادل مثل الرطوبة ونفاذية الغشاء بالإضافة إلى سماكته. يمكن حساب المقاومة الأومية للغشاء تبعًا لكمية المياه الموجودة ضمن الغشاء وتبعًا لتغير سماكته. فالرطوبة والانتشارية لهما تأثير مباشر على المردود وعلى أداء الخلية، لذا يجب العمل على تصريف الكمية الزائدة من الماء المتولد ضمن الغشاء.
Critical review
دراسة نقدية: يعتبر هذا البحث ذو أهمية كبيرة في مجال تحسين أداء خلايا الوقود الهيدروجينية، حيث يقدم تحليلاً شاملاً لتأثير توزيع الماء على أداء الخلية. ومع ذلك، يمكن أن يكون هناك بعض التحسينات الممكنة. على سبيل المثال، يمكن أن تكون الدراسة أكثر شمولية إذا تضمنت تجارب عملية لدعم النتائج النظرية. كما أن التركيز على تأثير العوامل البيئية الأخرى مثل الضغط ودرجة الحرارة المتغيرة يمكن أن يضيف قيمة إضافية للبحث. بالإضافة إلى ذلك، يمكن أن يكون هناك توضيح أكبر للمنهجية المستخدمة في النمذجة والمحاكاة لتوفير فهم أعمق للقراء.

Hydrogen production, vector of energy, by water electrolysis can be economically
viable by using electrical energy from renewable sources such as photovoltaic solar
energy. In this research was the study of solar hydrogen production using electroly
ser
based on polymeric exchange membrane electrolysis technology manufactured locally at
the Faculty of Technical Engineering in Tartous. The experimental studies were achieved
in two different methods: the first, direct coupling to the hydrogen electrolyser with PV
module. The second method, designed PV-electrolyzer system consists of the following
components: PV module, a maximum power point tracker (MPPT), A DC-DC converter,
which is used to operate the system at the maximum power of the PV system at all times
and to supply the necessary DC current to the electrolyzer, and tank hydrogen. The results
showed that the second method more effective and highly efficient when compared with
the first method because of the change in the intensity of solar radiation during the day.
Also, results show that some additives such as (KOH) play an important role in enhancing
the ionization process of the electrolyte liquid and improve process flow.

The Sediment microbial Fuel Cell (SMFC) has been studied in terms of electrical power generation, and water treatment. With the aim to design the Sediment Microbial Fuel Cell (SMFC), the sediment was brought from the Al-sonobar River bed, where it wa
s described to indicate the organic content and nutrients in it. The cell was equipped with a surface aeration system and started working in it. Where it monitored the electrical current and water pollution indicators over time. Later the aeration mode was changed and previous measurements of electricity generation, water pollution indicators were carried out, and compared with the previous stage. Results of the first mode of aeration have shown that the greatest value for Short Circuit Current (ISC) was (0.905) mA while the greatest value for Open Circuit Voltage (VOC) was (0.390) V. While a rise in current and voltage values was observed in the second mode of aeration, in which the greatest value of Short Circuit Current was (1.240) mA, and the greatest value of open circuit voltage (0.430) V. When the circuit has been connected to an external resistance R=100 Ω, the values for current, voltage, current density and power density were (0.805) mA, (0.084) V, (3.18) mA/m2, and (0.269) mW/m2, respectively. For water analysis, an increase in pH values of 8.90 was observed. The efficiency of removing of Chemical Oxygen Demand (COD), phosphates, nitrates and Total Dissolved Salts (TDS) has also increased, reaching: 72.11%, 62.70%, 35.60%, and 30.61%, respectively.
The research aims to reach fuel conservation opportunities and environment Protection while heating the water, by comparing the most common uses of primary and secondary energy carriers in our country . For example, water heating using electricity ge
nerated by fuel oil and gas, or the direct use of gas and diesel oil for water heating.
The coast of heating the water domestic uses was calculated by various ways, in order to find a low coast method and to avoid environmental damage.
In this research ,the conservation of primary energy for water heating while using gas and diesel oil boilers, was 4 times larger compared to the use of electricity generated by gas and fuel oil .As a result, the coast of water heating using gas burner was 4 times lower, while the coast of water heating using gas boiler was 10 times lower, compared to the coast of electricity heating method. this research also showed, that the use of gas fuel , is the best water heating method, concerning fuel conservation and environment Protection.
This environmental research was conducted on the coastal water of Tartous city for the first time to complement previous studies along the Syrian coast. Sampling station were selected based on their different environmental characteristics from each o
thers on one hand, and their continuous exposure to the sources of pollution (oil, chemical, organic) on the other hand. It hasbeen implemented13sortiesfreelyduring the study period, which lasted fromSeptember2013untilSeptember2014. during which water samples were collected for analysis and determine the concentration of nutrients in, as vital samples to study and determine the types of phytoplankton, which collected, in addition to conducting field measurements of some properties Physical seawater (temperature, pH, salinity, oxygen dissolved concentration). This study has recorded 160 species of phytoplankton in study sites, distributed as follows: 91 species of Chryssophyta, 50 of Pyrrophyta, 11 of Chlorophyta, and 8 of Cyanophyta, their distribution has differed from one site to another and from month to monthaccordingto the differentiation in the environmental conditions.
