Equivalent Electrical Circuit Modeling of Ceramic-Based Microbial Fuel Cells Using the Electrochemical Impedance Spectroscopy (EIS) Analysis
The effect of the thickness of ceramic membrane on the productivity of microbial fuel cells (MFCs) was investigated with respect to the electricity generation and domestic wastewater treatment efficiencies. The thickest ceramic membrane (9 mm) gained the highest coulombic efficiency (27.58±4.2 %), voltage (681.15±33.1 mV), and current and power densities (447.11±21.37 mA/m2, 63.82±10.42 mW/m2) ...
متن کاملStudy of Alkaline Electrodes for Hybrid Polymer Electrolyte Fuel Cells
Hybrid polymer electrolyte fuel cells combine a proton exchange membrane PEM and anion exchange membrane AEM and exhibit unique advantages. The electrochemical performance and current limitations of a hybrid cell with an alkaline electrode fabricated on a Nafion membrane was characterized at 70°C as a function of relative humidity. To separate the individual characteristics of the AEM anode and...
متن کاملCatalyst supports for polymer electrolyte fuel cells.
A major challenge in obtaining long-term durability in fuel cells is to discover catalyst supports that do not corrode, or corrode much more slowly than the current carbon blacks used in today's polymer electrolyte membrane fuel cells. Such materials must be sufficiently stable at low pH (acidic conditions) and high potential, in contact with the polymer membrane and under exposure to hydrogen ...
متن کاملAdvanced Materials in Polymer Electrolyte Fuel Cells
Polymer electrolyte fuel cells (PEFCs) have attracted much interest due to the need for an efficient, non-polluting power source with high energy density for vehicles in urban environments, as well as portable electronics [...].
متن کاملModeling transport in polymer-electrolyte fuel cells.
In this review, we have examined the different models for polymer-electrolyte fuel cells operating with hydrogen. The major focus has been on transport of the various species within the fuel cell. The different regions of the fuel cell were examined, and their modeling methodologies and equations were elucidated. In particular, the 1-D fuel-cell sandwich was discussed thoroughly because it is t...
