Proton Exchange Membrane Fuel Cells (PEMFC) suffer from a limited lifespan, which impedes their uses at a large scale. From this point of view, prognostics appears to be a promising activity since the estimation of the Remaining Useful Life (RUL) before a failure occurs allows deciding from mitigation actions at the right time when needed. Prognostics is however not a trivial task: 1) underlyin...

Polymer electrolyte membrane fuel cells (PEMFC) fed with H2 contaminated with CO may exhibit oscillatory behavior when operated galvanostatically. The self-organization of the anodic overpotential is interesting because it can be accompanied by an increase in the average performance. Herein we report experimental studies of voltage oscillations that emerge in a PEMFC equipped with a Pd/C or PdP...

An improved PEMFC model is developed. The improvement of the model includes modification for electrochemical reaction and mass transfer limitation at cathode and anode side. Global sensitivity analysis is used for evaluating the sensitivity of the model in parameter estimation. The simulation results reveal that estimated mass transfer coefficients depend on current density. The comparison show...

As a solution of high efficiency and clean energy, fuel cell technologies, especially proton exchange membrane fuel cell (PEMFC), have caught extensive attention. However, after decades of development, the performances of PEMFCs are far from achieving the target from the Department of Energy (DOE). Thus, further understanding of the degradation mechanism is needed to overcome this obstacle. Due...

With the increasing application of distributed energy resources and information technologies in the electricity infrastructure, innovative possibilities for incorporating the demand side more actively in power system operation are enabled. At the residential level energy costs could be reduced with intelligent price-based control concepts (demand response). A promising, controllable, residentia...

The key to overcome PEMFC cold start failure is raise the stack temperature above 0 °C before electrochemical reaction. As reaction progresses, heat released inside stack, which will stack. This heating method called passive heating, referred as PH in this article. Another method, active or simplified AH article, involves artificially adding a device input extra increase more quickly and reduce...

Proton exchange membrane fuel cell (PEMFC) has become one of the new energy vehicle powertrains due to its special advantages, such as no pollution environment, high efficiency and power density. In order improve performance, a three-dimensional simulation model actual PEMFC is constructed. Combined with mathematical models electrochemical current conservation model, calibrated by experiments. ...
