“…A CO-tolerant anode catalyst with lower metal loadings in alkaline media would also allow the use of reformed hydrogen with improved performances. Finally, major cost, physical size, and machinability concerns with traditional graphite-based bipolar plates have stimulated research into thinner, cheaper, and more easily machined metal bipolar plates (such as stainless steels) [44][45][46]. There are, however, significant corrosion problems associated with such metal plates and acidic PEMs.…”

This article introduces the radical approach of applying alkaline anion-exchange membranes (AAEMs) to meet the current challenges with regards to direct methanol fuel cells (DMFCs).A review of the literature is presented with regards to the testing of fuel cells with alkaline membranes (fuelled with hydrogen or methanol) and also to candidate alkaline anionexchange membranes for such an application. A brief review of the directly related patent literature is also included. Current and future research challenges are identified along with potential strategies to overcome them. Finally, the advantages and challenges with the direct electrochemical oxidation of alternative fuels are discussed, along with how the application of alkaline membranes in such fuel cells may assist in improving performance and fuel efficiency. KeywordsLow temperature, Alkaline anion-exchange membrane, Direct methanol fuel cell, Polymer electrolyte fuel cell.

“…6 The voltage drop across the specimen located in the middle of two copper plates was measured as a function of the force up to 500 N. 3,10,11 Two pieces of conducting carbon paper were inserted between the sample plate and copper plates. An electrical current (1A) was provided through the two copper plates.…”

The corrosion resistance of 316L stainless steel coated with NiO-YSZ (Ni added yttria stabilized zirconia) was examined in a proton exchange membrane fuel cell (PEMFC) environment. The NiO-YSZ coating was carried out using a sol-gel dip coating method, and the corrosion resistance and interfacial contact resistance (ICR) were determined by the composition and morphology of the NiO-YSZ film. The corrosion resistance increased with increasing Ni content in the NiO-YSZ film, but rapid corrosion was observed when the YSZ film contained more than 15 wt % Ni due to surface cracks. The polarization resistance was improved by several orders of magnitude when 316L stainless steel was coated with a 15 wt % NiO-YSZ film compared to bare 316L. The ICR of the NiO-YSZ film was decreased to that of bare 316L when the YSZ film contained 25 wt % NiO, suggesting the possible application of NiO-YSZ coated stainless steel for a bipolar plate.

“…Davies et al [14] indicates that compared to tested metal alloys the graphite material exhibits the lowest interfacial resistance. The resistance values (measured with a compaction force of 220 N/cm² similar to the force imposed in a fuel cell) of the metal alloys decrease in the order 321 1 > 304 1 > 347 1 > 316 1 > Ti > 310 1 > 904 1 >Incoloy 800 1 > Inconel 601 1 > graphite.…”
