The analysis for the efficiency properties of the fuel cell engine

Techno-economic assessment of hydrogen and power production from supercritical water reforming of glycerol

“…FC : electrochemical efficiency of the battery (=0.45[18]) _ m H 2 : mass flow-rate of hydrogen entering the stack (kg/s) LHV H 2 : lower heating value of hydrogen 1.2 Â 10 5 kJ/kg Accordingly, to produce 1 kW will be needed in the stack 33.3 mol/h of H 2[19].…”

Fuel cycle comparison of distributed power generation technologies.

“…Some of the observed variation is attributed to incomplete reporting of the basis of the reported efficiency (e.g., higher heating value [HHV] vs. lower heating value [LHV]) and whether or not the parasitic power consumption is included in the reported efficiency. Other factors affecting a particular fuel cell's net electrical efficiency include fuel utilization ratio, stack temperature, stack pressure drop, and power management control, in addition to ohmic resistance and polarization losses (Campbell et al 2003;Hou et al 2007). Additionally, technological advances result in improved fuel cell performance over time.…”
