“…Firstly, metallic molybdenum is not good at resisting corrosion by acid or saline electrolyte. Secondly, TieMoeN films form in solid solution structure with single TiN phase, instead of the nanocomposite microstructure as described in our previous study [19]. The former, to some extent, destroys the integrity of TiN crystalline lattice and brings dislocation and internal stress in, definitely leading to degradation in corrosion resistance.…”

“…The performances produced by this modified plate in both the fuel cell and the electrolyzer modes have been presented in Figure . Ti‐Ag‐N nanocomposite films, with honeycomb‐like morphology, were synthesized by employing pulsed bias arc ion plating technique . These films were then coated onto Ti bipolar plates.…”

Severe crisis of energy that our planet is going to face in the near future demands rapid development of alternative energy harnessing and storing devices. Various alternative energy devices have been developed so far, including solar cells, batteries and fuel cells, in order to compete and replace the traditionally used fossil fuel based energy technologies. A very recent addition to the list of such devices is the unitized regenerative fuel cell (URFC), which can function as a dual, i.e., electrolyzer‐cum‐fuel cell, device. In remote areas, where utilization of conventionally used energy sources results in high expense, URFC can serve as the best energy option, due to its relatively low cost, high efficiency and light weight. URFC utilizes bifunctional electrodes, which function in a dual mode of water electrolysis and fuel cell. The prime focus of URFC research has been to develop various low cost and highly efficient catalysts and catalyst supports towards the fabrication of alternative bifunctional electrodes and to fabricate strong and efficient bipolar plates. The aim of this review is to highlight the main outcomes of these aspects of research on URFCs.

“…Researchers have suggested changing the surface topology of BPP viz., surface treatment [32] and conductive coatings [33][34][35] as the possible solutions to reduce Interfacial Contact Resistance (ICR). Oyarceet et al [36] observed a decrease in contact resistance with respect to the temperature and relative humidity (RH) of gasses.…”

Unitized regenerative fuel cell (URFC) is considered to be the compact solution to generate and utilize hydrogen. It possesses combined capabilities of operating in fuel cell and electrolyser modes. In the present study, the performance of a URFC in electrolyser mode is modelled and also experimentally validated. The performances are being modelled using a combination of structural and CFD analysis tool. The effect of the operating gas pressure arising from the variation in the contact pressure between GDL and BPP on the performances are studied. The clamping pressure, as well as the operating pressure of the electrolyser, are seen to have a high impact on the contact resistance and thereby the performance as well. It is observed that the simulated polarization behavior is in good agreement with the experimental results. To restrict the area specific resistance below 150 mΩ cm 2 the operating pressure should be maintained below 5.9 bar at clamping pressure of 1.5 MPa.
