“…Usually when preparing MEAs and before their usage, it is recommended to apply hot-press to properly embed the catalyst layer into the membrane [24], promoting good contact within the three-phase region [25] and alleviating ohmic losses [26], thus to achieve better PEM electrolysis performance and to avoid catalyst delamination [27]. We investigated the effects of hot-press on PEM electrolysis performance using 9 wt%, 33 wt% and 47 wt% MoS 2 /Vulcan.…”

“…PEMFCs represent an interesting power source solution due to their low operation temperature, high power density, good response to varying loads, and easy scale-up [1]. However, the high cost of this technology makes modelling, parametric identification and fault diagnosis necessary research topics to improve the use of PEMFCs [2].…”

Proton Exchange Membrane Fuel Cell (PEMFC) fuel cells is a technology successfully used in the production of energy from hydrogen, allowing the use of hydrogen as an energy vector. It is scalable for stationary and mobile applications. However, the technology demands more research. An important research topic is fault diagnosis and condition monitoring to improve the life and the efficiency and to reduce the operation costs of PEMFC devices. Consequently, there is a need of physical models that allow deep analysis. These models must be accurate enough to represent the PEMFC behavior and to allow the identification of different internal signals of a PEM fuel cell. This work presents a PEM fuel cell model that uses the output temperature in a closed loop, so it can represent the thermal and the electrical behavior. The model is used to represent a Nexa Ballard 1.2 kW fuel cell; therefore, it is necessary to fit the coefficients to represent the real behavior. Five optimization algorithms were tested to fit the model, three of them taken from literature and two proposed in this work. Finally, the model with the identified parameters was validated with real data.

“…A list of target highlights of metallic BPs can be found in [5]. The counterpart of the above-listed advantages is however a series of specific drawbacks, essentially related to corrosion resistance; in fact, exposure to FC environment can cause: (i) passivation modes giving rise to an increment of ohmic drop and (ii) release of corrosion products that can damage other FC components, such as gas-diffusion electrodes, ionexchange membranes and catalysts [6].…”

Abstract:In this paper we study the corrosion of AISI 304 austenitic stainless steel PEMFC bipolar plates in aqueous and room-temperature ionic-liquid electrolytes. The anodic potential thresholds and dynamics have been investigated by electrochemical (potentiodynamic and potentiostatic) and in situ spectroelectrochemical methods (visible electroreflectance and VIS-UV spectroellipsometry). We measured the values of damage potentials and we followed the time evolution of corrosion current and reflectivity above and below the pitting potential, obtaining an accurate characterisation of the surface conditions under oxidative attack. The ability of AISI 304 to repassivate in Cl -containing aqueous solution as well as the amount of residual surface damage have been assessed quantitatively by following electrode reflectivity under applied potential. Outstanding inertness of AISI 304 in [BMP][TFSA] was proved. The results of this work show that low-cost AISI 304 is a promising interconnect material for both Nafion-and RTIL-based PEMFCs.
