The cell design and experimental work was performed by Isaac Martens and Jakub Drnec using ESRF\u2019s ID31 beamline.<\/p>\n<p>We have constructed a 5\u202fcm<sup>2<\/sup> proton exchange membrane hydrogen fuel cell optimized for transparency of high energy X-rays. This cell allows for in situ elastic scattering measurements (WAXS, SAXS) during electrochemical operation with minimal trade-offs in cell performance vs benchtop designs, and is capable of reaching automotive current densities. A key feature is that the beam enters the cell at grazing incidence to the electrodes, massively increasing the effective pathlength and therefore the signal-to-background ratio. The transparency in the plane of the sample permits imaging coupled with advanced techniques, such as X-ray diffraction computed tomography.<\/p>\n<p><a href=\"http:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-2332\" src=\"http:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-1030x960.jpg\" alt=\"PEM fuel cells diag\" width=\"1030\" height=\"960\" srcset=\"https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-1030x960.jpg 1030w, https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-300x280.jpg 300w, https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-768x716.jpg 768w, https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-1500x1398.jpg 1500w, https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-705x657.jpg 705w, https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag-450x420.jpg 450w, https:\/\/www.finden.co.uk\/wp-content\/uploads\/2019\/08\/PEM-fuel-cells-diag.jpg 1566w\" sizes=\"auto, (max-width: 1030px) 100vw, 1030px\" \/><\/a><\/p>\n<p>The work was done at the The European Synchrotron (ESRF) and research partners included; University of British Columbia, Universit\u00e9 Grenoble Alpes, University of Helsinki, Aalto University, Baltic Fuel Cells and University College London.<\/p>\n<p>Read the article at <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775319308997\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775319308997<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Finden scientists\u2019 new work on the design and application of a new cell for proton-exchange membrane fuel cells has been published in a new paper, \u201cX-ray transparent proton-exchange membrane fuel cell design for in situ wide and small angle scattering tomography\u201d in the Journal of Power Sources.
