Abstract

Proton değişim membranı (PEM) yakıt hücreleri, son zamanlarda geleneksel motorlar için ümit vaat eden bir malzeme olarak büyük bir ilgi görmüştür. PEM yakıt hücre performansının, çalışma sıcaklığı ve gaz akışlarının nemlendirilmesi gibi birçok parametreden etkilendiği bilinmektedir. Bu çalışmada, Pt/C destekli tek hücreli PEM yakıt hücresi üretimi ve uygulaması için bir deney tasarımı dizayn edildi. PEM yakıt pilinin performans testleri, yakıt pili hücre çalışma sıcaklığı ve katalizör miktarları parametrelerine bağlı olarak incelendi. Farklı yakıt hücresi sıcaklıklarında ve farklı katalizör miktarlarında polarizasyon eğrileri elde edildi. Elde edilen veriler sonucunda; Co-B katalizörü için ideal voltaja göre %88, güce göre %56 ve Ni-B katalizörü kullanılarak gerçekleştirilen deneylerin sonucunda ise, ideal voltaja göre verim %83 ve güce göre verim ise %54 olarak hesaplandı.

Polymer Electrolyte Membrane Fuel Cell Indirect Operation with Sodium Borohydride

Abstract

Proton exchange membrane (PEM) fuel cells have drew great notice of last years as a promising modification for traditional engines. The performance of PEM fuel cells is known to be affected by many parameters such as operating temperature and humidification of the gas streams. In the present study, an experimental design for the production and application of Pt / C supported single cell PEM fuel cell was designed. The performance tests of the PEM fuel cell were examined depending on the fuel cell operating temperature and catalyst amounts parameters. Polarization curves were obtained by using different amounts of catalysts and different fuel cell operating temperatures. As a result of the data obtained; As a result of the experiments carried out using the Ni-B catalyst for the Co-B catalyst, 88% relative to the ideal voltage, 56% based on the power and the efficiency based on the Ni-B catalyst, the efficiency was calculated as 83% and the yield based on the power was 54%. In addition, ideal voltage values were measured between 0.87 volts and 1.1 volts.
