Original scientific paper Numerical simulations of four combustion processes in a dual-fuel combustor of chemically recuperated gas turbine (CRGT) were carried out in this work. The fuels in the four combustion processes were liquid fuel, liquid fuel + steam, liquid fuel + reformed gas and reformed gas, respectively. The mathematical models adopted for different fuels combustion consist of real...

This paper introduces a micro direct methanol fuel cell (μDMFC) with an imbedded self-pumping mechanism to deliver liquid fuel. The fuel is propelled without any power consuming component (e.g., a pump), while removing the CO2 bubbles generated by the fuel-cell electrochemical reaction of the system. Furthermore, the pumping rate is self-regulated by the reaction, i.e., by the load. By eliminat...
