“…For addressing that issue, engineering research has been focusing on nuclear and fuel cell technologies [1][2][3][4][5][6]. However, since nuclear waste management [7,8] and fuel cell reliability [9][10][11][12][13][14] are unresolved challenges, these technologies appear to be unsustainable and unfeasible. Currently, the green economy strategy is developed for addressing all issues with proactive balanced approaches.…”

Since industrial revolution, human activities drive towards unsustainable global economy due to the overexploitation of natural resources and the unacceptable emissions of pollution and greenhouse gases. In order to address that issue, engineering research has been focusing on gas sensors development for monitoring gas emissions and controlling the combustion process sustainability. Semiconductors metal oxides sensors are attractive technology because they require simple design and fabrication, involving high accessibility, small size and low cost. Perovskite oxides are the most promising sensing materials because sensitivity, selectivity, stability and speed-response can be modulated and optimized by changing the chemical composition. One of the most convenient synthesis process of perovskite is the citrate-nitrate auto-combustion method, in which nitrate is the oxidizing agent and citrate is the fuel and the chelating argent in the same time. Since the sensibility of perovskite oxides depends on the defective crystallographic structure and the nanomorphology, the experimental was designed in order to study the dependence of powder properties on the synthesis conditions, such as the solution acidity and the relative amount of metals, nitrates and citric acid. Crystalline structure was studied in depth for defining the effects of synthesis conditions on size, morphology and crystallographic structure of nanopowders of LaFeO3

“…Bipolar plates (BPPs) for PEMFC have been investigated extensively [4][5][6][7][8][9][10][11][12][13][14][15], while few reports have been presented on the BPPs for URFCs. The operating environment of URFCs in water electrolysis (WE) mode is much harsher than that in fuel cell (FC) mode.…”

“…In order to simulate an environment typical of the prolonged operation of traditional, Nafion-based PEMFCs, we employed aqueous solutions containing Cl and SO 4 2 ions. The presence of SO 4 2 ions is due to Nafion degradation [2], while that of Cl ions derives from pollution of reactant gases or to the degradation of MEA, since chlorine is employed for its production [12]. The RTIL was used in its pure form in order to emphasise its specific corrosivity.…”

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.
