“…Techniques related to current control that are used for other purposes might also be introduced to the conditioning process. A high-frequency ripple current has reportedly been used for an aging test [18]. The current ripple is produced by submitting the output fuel cell current to a high-frequency switch.…”

a b s t r a c tA newly fabricated polymer electrolyte membrane (PEM) fuel cell usually needs a so-called breakin/conditioning/incubation period to activate it and reach its best performance. Typically, during this activation period the cell performance increases gradually, and then reaches a plateau without further increase. Depending on the membrane electrode assemblies, this process can take hours and even days to complete, which consumes a considerable amount of hydrogen fuel, leading to a higher operating cost. To provide for accelerated conditioning techniques that can complete the process in a short time period, this paper reviews established conditioning protocols and reported methods to condition PEM single cells and stacks, in an attempt to summarize available information on PEM fuel cell conditioning and the underlying mechanisms. Various techniques are arranged into two categories: on-line conditioning and off-line conditioning. For each technique, the experimental procedure and outcomes are outlined. Finally, weaknesses of the currently used conditioning techniques are indicated and further research efforts are proposed.Crown

“…Additionally, an inverter is usually integrated to the system for conversion to alternative current. The high frequency (HF) and low frequency (LF) current ripples generated by the presence of power electronic converters, can induce accelerated performance decrease , , degradation of the MEA , electrochemical active surface area (ECSA) decrease , and gas diffusion layer (GDL) degradation .…”

Direct Coupling of PEM Fuel Cell to Supercapacitors for Higher Durability and Better Energy Management

A single polymer electrolyte fuel cell has been directly hybridized to a stack of three supercapacitors: the system formed has been investigated in operation in the fuel cell dynamic load cycle, which emulates the energy demand in transported applications. Comparison with regular, non‐hybridized fuel cell operation was analyzed in terms of hydrogen consumption in the case that the gas flow rates are directly controlled by cell current during the cycles with constant gas stoichiometric factors: the smoothening effect of the supercapacitors in the overall circuit leads to more even profiles of the cell current and voltage in the cycle, which allows safer and better hydrogen consumption management in this regime: the average H2 consumption per cycle could be reduced by 16% without change of the overall energy produced. Besides, the runs were conducted over more than 1,300 hours with evaluation of the fuel cell performance and capacity at regular intervals, with or without hybridization. A moderate positive effect of hybridization was observed in the time variations of the voltage‐current curves and the fuel crossover. However, the resistances for ohmic, charge transfer and diffusion phenomena, were not so much improved by the hybridization, in spite of less sharp voltage.

“…[12][13] As the dc-dc converter injects less current ripple into the source, the efficiency as well as the life span can be increased with that for the PV or FC array. [14][15] The voltage build up can be possible by Boost Converter (BC) and Cascaded Boost Converter (CBC). [16][17]BC cannot give the significant build up of output voltage for the same duty ratio as compared to CBC as the output voltage of the later one is a quadratic function of duty cycle.…”

In this paper, an overall comparison between the Quadratic Boost Converter (QBC) & Cascaded Converter or Cascaded Boost Converter (CBC) is given in terms of ideal condition, as well as with the consideration of Equivalent Series Resistance (ESR) of inductor-capacitor. The differences in the voltage gain due to the individual effect of inductive and capacitive ESR is shown in this paper. The parameters of the converters are found out with a consideration of per unit ripple quantity of inductor current and capacitor voltage. It is seen that in QBC & CBC voltage gain is same but the power stress rating of the switch in prior one is more compared to the later. At the end, the simulation results of both the converters are given for a 20V/98V, 100 W output. The analysis and simulation results are presented in this paper for the verification of the feasibility.
