Electrochemical model of solid oxide fuel cell for simulation at the stack scale. Part II: Implementation of degradation processes

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Arata Nakajo, Pietro Tanasini

The degradation of the electrochemical performance of solid oxide fuel cell (SOFC) devices is a major hurdle to overcome before commercialisation. The interplay between the phenomena and the long testing times complicate the research, which highlights the ...

Development and Studies of Novel Microfabricated Radiation Hard Scintillation Detectors With High Spatial Resolution

Philippe Renaud, Alessandro Mapelli, Sébastien Jiguet, Noelia Vico Triviño

A new type of scintillation detector is being developed with standard microfabrication techniques. It consists of a dense array of scintillating waveguides obtained by coupling microfluidic channels filled with a liquid scintillator to photodetectors. Easy ...

Enhancement of microcrystalline n-i-p solar cell performance via use of pre-covering layers and H-2 treatment

Christophe Ballif, Franz-Josef Haug, Xavier Niquille, Vanessa Terrazzoni-Daudrix

We study the effects of a-Si:H and mu c-Si:H covering layers and an H-2 treatment on the characteristics of mu c-Si:H thin film solar cells deposited in open single chamber very high frequency plasma enhanced chemical vapor deposition systems. Secondary io ...

Cathodic shift in onset potential of solar oxygen evolution on hematite by 13-group oxide overlayers

Michael Graetzel, Kevin Sivula, Nicolas Tétreault, Florian Le Formal, Maurin Cornuz, Jérémie Minh-Châu Brillet, Takashi Hisatomi

The onset potential of photoelectrochemical water oxidation on ultrathin hematite was improved by up to 200 mV by the chemical bath deposition of 13-group oxides as overlayers. It is proposed that the corundum-type overlayers released lattice strain of the ...

Planar micro-direct methanol fuel cell prototyped by rapid powder blasting

Martinus Gijs, Meng Shen, Ludovic Dovat

We present a planar micro-direct methanol fuel cell (μ−DMFC) fabricated by rapid prototyping powder blasting technology. Using an elastomeric mask, we pattern two parallel microfluidic channels in glass. The anode and cathode of the fuel cell are formed by ...

Film Condensation of R-134a and R-236fa, Part 1: Experimental Results and Predictive Correlation for Single-Row Condensation on Enhanced Tubes

John Richard Thome, Mathieu Habert, Marcel Christians

New predictive methods for falling film condensation on vertical arrays of horizontal tubes using different refrigerants are proposed, based on visual observations revealing that condensate is slung off the array of tubes sideways and significantly affects ...
