  bibo_abstract:
  - A comparative, experimental diffusivity study of gas diffusion layer (GDL) materials
    for polymer electrolyte fuel cells (PEFC) is presented for the first time. The
    GDL plays an important role for electrochemical losses due to gas transport limitations
    at high current densities. Characterization and optimization of these layers is
    therefore essential to improve power density. A recently developed method which
    allows for fast diffusimetry is applied and data compared to the literature values.
    Measurements are made as a function of direction and compression and the effect
    of different binder structures and hydrophobic treatments on effective diffusivities
    are discussed. A better understanding of the results is gained by including novel
    GDL cross-section images and a meaningful unit cell model for the interpretation
    of the data. The diffusivity data is valuable for GDL manufacturers and future
    PEFC models. The study reveals that a binder–fiber ratio larger than 50% has a
    negative impact on the effective diffusion properties. The hydrophobic treatment
    which is necessary to improve the water management can impede diffusion and thus
    reduce the power density. Furthermore binder has an isotropic effect while compression
    pronounces the in-plane orientation of the fibers.@eng
