..., the combustion duration, combustion mass ratio, and flame height decrease significantly by 40%. The electrolyte achieves non-flammability when the additive fraction increases to 40%. It is observed that with DMMP addition the charred layer forms on the surface of electrolyte liquid, and slows down the heat...

... ) and a limited ability to thermal cycle (<200 cycles). Recently, a novel hybrid setup that combines a fuel-rich combustion reformer with a SOFC was developed and utilized to investigate rapid heating, cooling, and thermal cycling of a micro-tubular SOFC. In this work, 3000 moderate thermal cycles...

Mass, momentum, energy, and species balance equations were simultaneously calculated with the chemical reactions...

... full conversion and the adiabatic temperature are not reached at the outlet, as shown in Figs. 7a 7b . The wall temperature increases immediately at the channel entrance because of exothermic hydrogen and CO combustion in the region close to the wall (Fig. 7b ). For faster flow the wall...

... and stationary components to the off-design conditions. The method leads to the definition of the operating space of the hybrid system, thus allowing detection of optimal choices for an efficient part-load operation. The computational fluid dynamics (CFD)-based analysis of the combustion chamber is addressed...
