SnO2:F coated ferritic stainless steels for PEM fuel cell bipolar plates

The stability of illuminated p-GaInP2 semiconductor photoelectrode

“…A calibration standard solution, containing 100 ppm of each of the metal ions was purchased from Inorganic Ventures, Inc. The estimated relative uncertainty for ICP analysis, mainly due to variability in the plasma, pump rate and nebulizer efficiency, is 5% [24].…”

Reviewing Metallic PEMFC Bipolar Plates

“…It is noticed that the behaviour of SnO 2 :F-coated steels depends strongly on the substrate steel. In view of the corrosion resistance in simulated PEMFC environments, SnO 2 :F behaved excellent on 349™, 446 and 2205 SSs [104][105][106]. The corrosion resistance of the other SSs (like 317L and 444) was also improved.…”

“…Conductive SnO 2 :F coating has been also investigated at the National Renewable Energy Laboratory (NREL) [104][105][106][107] as a feasible coating to protect metallic substrate from corrosion and also to provide a better surface conductivity, which is due to the stability of the coating in most environments, expertise of NREL in the application of the coating, and the low-cost consideration. It is noticed that the behaviour of SnO 2 :F-coated steels depends strongly on the substrate steel.…”

Corrosion Performance of Austenitic Stainless Steel Bipolar Plates for Nafion- and Room-Temperature Ionic-Liquid-Based PEMFCs

“…The published durability test methods include: (i) open circuit potential measurements [7][8][9][10][11][12][13][14][15], (ii) potentiostatic polarisation [7][8][9][10][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30], (iii) polarisation resistance [27,31,32], (iv) linear-sweep voltammetry [7,33,34], (v) I-V and I-P curves and life time tests in fuel-cell *Address correspondence to this author at the Dipartimento di Ingegneria dell'Innovazione, Università del Salento, via Monteroni, 73100 Lecce, Italy; Tel: +39 0832297621, +39 0832297290; E-mail: benedetto.bozzini@unisalento.it assemblies [24,[35][36][37].
