Integration of Reversible Solid Oxide Electrolysis (rSOC) to Wastewater Treatment Plants for Sustainable Green Gas Production and Balancing of Green Power
Autor: Robert Weiss, Markus Rautanen, Ville Saarinen, Jari Kiviaho, Jari Pennanen, Olli Himanen
Publikováno v: ECS Transactions. 111:1639-1655
Biogas produced from anaerobic digestion (AD) of sewage sludge and organic wastes at wastewater treatment plants (WWTPs) can present an important energy contribution to a sustainable society. Raw AD biogas contains 50-65 molar% methane (CH4) and 50-3

Compression Properties and Leakage Tests of Mica-Based Seals for SOFC Stacks
Autor: Markus Rautanen, Olli Himanen, Jari Kiviaho, Ville Saarinen
Publikováno v: Rautanen, M, Himanen, O, Saarinen, V & Kiviaho, J 2009, ' Compression properties and leakage tests of mica-based seals for SOFC stacks ', Fuel Cells, vol. 9, no. 5, pp. 753-759 . https://doi.org/10.1002/fuce.200900029
Sealing properties and compression properties of two mica‐based materials, Thermiculite 866 and Statotherm HT were measured. Thermiculite 866 was tested in two forms: as‐made and precompressed (consolidated). Sealing tests were carried out at 800

A 3D model for the free-breathing direct methanol fuel cell: Methanol crossover aspects and validations with current distribution measurements
Autor: Ville Saarinen, Olli Himanen, Tanja Kallio, Göran Sundholm, Kyösti Kontturi
Publikováno v: Journal of Power Sources. 172:805-815
A three-dimensional model has been developed for the free-breathing direct methanol fuel cell (DMFC) assuming steady-state isothermal and single-phase conditions. Especially the MeOH crossover phenomenon is investigated and the model validations are

Current distribution measurements with a free-breathing direct methanol fuel cell using PVDF-g-PSSA and Nafion® 117 membranes
Autor: Tanja Kallio, Ville Saarinen, Göran Sundholm, Olli Himanen, Kyösti Kontturi
Publikováno v: Journal of Power Sources. 163:768-776
The methanol crossover and other mass transfer phenomena have been investigated in a free-breathing direct methanol fuel cell (DMFC). The current distribution profile along the MeOH flow channel was measured and information of local concentrations of

Characterization of the novel ETFE-based membrane
Autor: Kyösti Kontturi, Ville Saarinen, Mikael Paronen, Tanja Kallio, Mikko Karesoja
Publikováno v: Journal of Membrane Science. 280:20-28
Recently developed ETFE-SA membrane (sulphonated poly(ethylene-alt-tetrafluoroethylene)) has proved to be chemically stable in the direct methanol fuel cell (DMFC). According to methanol permeability measurements, the MeOH permeability through the ET

New ETFE-based membrane for direct methanol fuel cell
Autor: Pertti Tikkanen, Tanja Kallio, Mikael Paronen, Ville Saarinen, Kyösti Kontturi, Eero Rauhala
Publikováno v: Electrochimica Acta. 50:3453-3460
The investigated membranes are based on 35 μ m thick commercial poly(ethylene-alt-tetrafluoroethylene) (ETFE) films. The films were made proton conductive by means of irradiation treatment followed by sulfonation. These membranes have exceptionally
