in this paper, a hybrid solid oxide fuel cell (sofc) and micro gas turbine (mgt) power system is parametrically studied to evaluate the effect of different operating conditions. the sofc/mgt power system includes sofc reactor, combustion chamber, compressor and turbine units, and two heat exchangers. the effects of fuel utilization, temperature, and pressure are assessed on performance of the h...

When connected in small amounts, the impact of distributed generation (DG) on distribution system stability will be negligible. However, if its penetration level becomes higher, distributed generation may start to influence the dynamic behavior of the system as a whole. This paper presents a mathematical representation of a solid oxide fuel cell plant that is suitable for use in distribution sy...

The polymer electrolyte membrane fuel cell is a power source with the potential for reducing green-house gas emissions. Characterizing the electrolyte of a fuel cell is an important procedure for assessing the performance of the entire device. Atomic force microscopy (AFM) is one of the major instruments for such characterization, since it can be used for determining the surface potential and/o...
