    <title language="eng">On the structural composition and stability of Fe–N–C catalysts prepared by an intermediate acid leaching</title>
    <abstract language="eng">The development of highly active and stable&#13;
non-noble metal catalysts (NNMC) for the oxygen reduction&#13;
reaction (ORR) in proton exchange membrane fuel cells&#13;
(PEM-FC) becomes of importance in order to enable cost&#13;
reduction. In this work, we discuss the structural composition as derived from Fe-57Mößbauer spectroscopy and X-ray diffraction, catalytic performance determined by a rotating (ring)disk electrode (RRDE) technique and stability evaluation of our Fe–N–C catalysts prepared by an intermediate acid leaching (IAL). The advantage of this IAL is given by a high density of active sites within the catalyst, as even without sulphur addition, an iron carbide formation and related disintegration of active sites are inhibited. In addition, our accelerated stress tests illustrate better stability of the sulphur-free&#13;
IAL catalyst in comparison to the sulphur-added one.</abstract>
