Internal combustion engines have been widely used for past 100 years. In the development of engine components a number of special techniques are used to compact the hostile operating environment, which usually includes ...

Cell temperature and selection of the reactant gases are crucial parameters for the design and optimization of fuel cell performance. In this study, effect of operating conditions on the performance of solid oxide fuel ...

In this study, the effects of hydrogen flow rate, oxygen flow rate, cell and humidification temperature on power density were examined experimentally. The experiments have been carried out on a single proton exchange ...

In this study, the response surface methodology (RSM) has been applied to optimize the operating conditions of direct methanol fuel cell (DMFC). A quadratic model was developed through RSM in terms of related independent ...

In this study, a three-dimensional, single-phase model has been established to investigate the performance of proton exchange membrane fuel cell (PEMFC) with serpentine flow fields. The model was operated in the temperature ...

In this investigation, thermal and structural finite element analysis has been employed to analyse the level of stresses developed in Al2O3-spherical cast iron (SG), ZrO2-(12% Si + Al) and ZrO2-SG coatings subjected to ...

Düşük ısı kayıplı motor, seramik kaplama, dizel motoru. 1970'li yıllardaki petrol krizi ile birlikte tüm alanlarda enerji tasarrufu gündeme gelmiştir. Petrol esaslı yakıt rezervlerinin hızla tükenmesi, yeni enerji kaynakları ...

Water and heat management are the most critical issues for the performance of proton exchange membrane (PEM) fuel cells. They can be provided by keeping hydrogen flow rate, oxygen flow rate, cell temperature and humidification ...
