“…The FC ancillaries (auxiliary services and control modules) has an important role in avoiding the oxygen starvation phenomenon [10,26], which destroys in time the FC stack [1,2]. Moreover, if they are appropriately controlled, then the hydrogen consumption may be reduced even under unknown load cycles that can produce uncertainties in FC operating parameters [8,27].…”

“…The fueling rate must be limited to avoid the fuel and oxidant starvation [4,34]. Gas starvation may also appear during the high slopes of the load profile [26]. So, understanding of the FCHPS dynamic behavior is a key factor in designing the EMU strategies [23,35,36].…”

“…The search speed of the proposed ES control scheme is higher, being limited to safe slopes recommended for the FC power profile [26] via a slope limiter. The DC bus voltage is maintained at 200 V So, the contributions at the level of the FCHPS topologies are the following: (1) two advanced fueling configurations are proposed and analyzed in comparison with the sFF control, which is usually used in practice [23,26]; (2) the LF control is proposed to operate the ESS in charge-sustaining mode, being simpler to be implemented compared to wavelet techniques shown in Ref.…”

-Water management is a critical factor in obtaining the highest performance and efficiency from polymer electrolyte membrane (PEM) fuel cells. The liquid water distribution in the individual layers of the PEM fuel cell has a strong impact on performance. The ionic conductivity of the membrane has a strong dependence on membrane hydration. The reactant gases in a PEM fuel cell are supplied through a humidification system to maintain appropriate levels of hydration in the membrane. However, the removal of the anode humidifier would significantly reduce the balance of plant costs and reduce the volume required for the fuel cell in an automotive setting. In this paper, the impact of lower anode humidification on the cell performance and the water distribution in the membrane and the cathode gas diffusion layer were studied. Synchrotron X-ray radiography was used to measure the changes in liquid water quantity in the individual layers. The impact of changing anode humidification on the water distribution is studied. The changes in membrane hydration levels have been measured by the radiographic technique and compared with the changes in membrane resistance.

“…The emissions from fossil fuel based power systems can be abated to a greater extent by substituting fossil energy with hydrogen energy [1]. To address this issue of emissions and reduce the burden on conventional power sources, PEM fuel cells are being considered as suitable power packs for both stationary [2][3][4] and transport applications [5][6][7][8]. Many research groups are focusing towards contamination, prevention and mitigation strategies to increase the durability of the PEMFC under practical conditions.…”

Performance analysis of polymer electrolyte membrane (PEM) fuel cell stack operated under marine environmental conditions

The marine environmental condition, especially NaCl, has been identified as one of the major sources of contamination on the performance of open cathode Proton Exchange Membrane Fuel Cells (PEMFC) system, when the power source is based on fuel cells for marine applications like submarines, navy ships etc., In the present paper, we have studied the performance of PEMFCs under the marine environment for a longer duration and also the recovery mechanism of the PEMFC power pack after contamination. It has been observed that the NaCl is a major contaminant for PEMFC, compared to NO x and SO x , which are major contaminants for fuel cells operating in the land regions. We have observed a performance loss of 60 % in PEMFC, when operated for 48 h, due to poisoning of PEMFC by NaCl vapours. The recovery of the stack is attempted by repeated water washing on the cathode side of the fuel cell, presuming that the salts get deposited only on the surface of the electrodes and the performance is easily recoverable. The recovery mechanisms are analysed by constant-current discharging operation and by modified experimental methods and are reported here. The performance vagaries in fuel cells due to sea water contamination is also analysed by linear fit and it is found that the rate of power increment after water wash is higher than the rate of power increment, around 11.5 W/10 h compared to normal environmental conditions, which is 4.1 W/10 h.
