Palladium, providing effective full oxidation of formate to CO2, has been widely used as FOR catalyst, but it suffers from low stability, moderate activity, and high cost. Herein, we detail a colloidal synthesis route for the incorporation of P on Pd2Sn nanoparticles. These nanoparticles are dispersed on carbon black and the obtained composite is used as electrocatalytic material for the FOR. The Pd2Sn0.8P-based electrodes present outstanding catalytic activities with record mass current densities up to 10.0 A mgPd-1, well above those of Pd1.6Sn/C reference electrode. These high current densities are further enhanced by increasing the temperature from 25 °C to 40 °C. The Pd2Sn0.8P electrode also allows for slowing down the rapid current decay that generally happens during operation and can be rapidly re-activated through potential cycling. The excellent catalytic performance obtained is rationalized using density functional theory (DFT) calculations.","lang":"eng"}],"scopus_import":"1","citation":{"chicago":"Montaña-Mora, Guillem, Xueqiang Qi, Xiang Wang, Jesus Chacón-Borrero, Paulina R.

Beside ensuring sufficient electrical and thermal contact between the whole electrode area and the flow field, these typically 200–400 μm thick porous structures enable the access of educts to the electrode area which would be occluded by the flow field lands if the flow field is directly attached to the electrode. Hence, the characterisation of properties pertaining to mass transport of educts and products through these structures is indispensable whilst examining the contribution of the GDLs to the overall electrochemical characteristics of a MEA. A fast and cost effective method to measure the effective diffusivity of a GDL is presented. Electrochemical impedance spectroscopy is applied to measure the effective ionic conductivity of an electrolyte-soaked GDL. Taking advantage of the analogy between Ficks and Ohms law, this provides a measure for the effective diffusivity. The method is described in detail, including experimental as well as theoretical aspects, and selected results, highlighting the anisotropy and dependence on the degree of compression, are shown. Moreover, a two-dimensional model consisting of regularly spaced ellipses is developed to represent the porous structure of the GDL, and by using conformal maps, the agreement between this model and experiment with respect to the sensitivity of the effective diffusivity towards compression is shown."}],"day":"01","page":"63-77","date_published":"2008-01-01T00:00:00Z","publication_status":"published","oa_version":"None","_id":"7322","author":[{"full_name":"Kramer, Denis","first_name":"Denis","last_name":"Kramer"},{"orcid":"0000-0003-2902-5319","last_name":"Freunberger","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","full_name":"Freunberger, Stefan Alexander","first_name":"Stefan Alexander"},{"first_name":"Reto","full_name":"Flückiger, Reto","last_name":"Flückiger"},{"last_name":"Schneider","first_name":"Ingo A.","full_name":"Schneider, Ingo A."},{"last_name":"Wokaun","full_name":"Wokaun, Alexander","first_name":"Alexander"},{"last_name":"Büchi","full_name":"Büchi, Felix N.","first_name":"Felix N."},{"first_name":"Günther G.","full_name":"Scherer, Günther G.","last_name":"Scherer"}],"type":"journal_article","status":"public","year":"2008","date_updated":"2021-01-12T08:13:03Z","publisher":"Elsevier","doi":"10.1016/j.jelechem.2007.09.014","language":[{"iso":"eng"}],"title":"Electrochemical diffusimetry of fuel cell gas diffusion layers","article_type":"original","volume":612,"publication":"Journal of Electroanalytical Chemistry","publication_identifier":{"issn":["1572-6657"]},"quality_controlled":"1","month":"01","intvolume":"       612","article_processing_charge":"No","issue":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","citation":{"apa":"Kramer, D., Freunberger, S.
