الملخص

وجود النافيون كعنصر أساسي من ضمن العناصر المكونة لطبقة الحافز في خلية الوقود ذات الغشاء البروتوني المبادل يؤدي الى اتساع مناطق اطوار الاتصال الثلاثة بين الغازات المتفاعلة والالكتروليت الصلب وسطح المحفز ويجعل طبقة الحافز أكثر نشاطا في ثلاثة ابعاد مما يمنح الايونات حرية الحركة خلال طبقة الحافز يؤدي بدوره الى تحسن أداء خلية الوقود ذات الغشاء البروتوني. ان الهدف الرئيسي من هذه الدراسة يتمحور في اختبار مدى اعتماد انسب كمية من النافيون على كتلة الحافز المتكون من عنصر البلاديوم المدعم بالكربون.
أظهرت نتائج هذه الدراسة أن القيمة المثلى لكمية النافبون الموجودة في طبقة الحافز تعتمد اعتمادا مباشرا وعلى صورة تناسب عكسي مع كمية الحافز في نفس الطبقة. فعندما تأخذ كمية الحافز المقادير cm2/mg 1.0 ± 0.4 و ± 2.3 ,cm2/mg 1.0 و ,cm2/mg 05.0 ± 45.2 فان النسب المثلى لكمية النافيون داخل طبقة الحافز والتي تمنح الخلية اعلى كفاءه هي 33 و 35 و %.wt 37 على الترتيب.
