  text: The deployment of direct formate fuel cells (DFFCs) relies on the development
    of active and stable catalysts for the formate oxidation reaction (FOR). 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.

  text: The gas diffusion layers (GDLs) of a membrane electrode assembly (MEA) serve
    as link between flow field and porous electrode within a polymer electrolyte fuel
    cell. 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.
