<span style="font-family:"Arial Narrow","sans-serif"">The oxygen electro-reduction reaction (ORR) is the cathode reaction in fuel cells, envisioned to replace combustion engines for transportation [1]. The first commercial vehicles powered by acidic-type H<sub>2</sub>/air
polymer fuel cells were released in 2015. The ORR being particularly sluggish, research on novel ORR catalysts is unabated since the 1990's. While novel Pt nanostructures have allowed decreasing the amount of precious metal [2], recent advances in the class
of metal-nitrogen-carbon (Me-N-C) catalysts has attracted attention [3-4]. Their development was initially inspired by macromolecules catalyzing ORR in the respiratory system of living organisms. Synthesized at
</span><span style="font-family:Symbol">³</span><span style="font-family:"Arial Narrow","sans-serif""> 700 °C, modern Me-N-C catalysts are the object of intense research regarding the nature/structure of active site and ORR mechanism. Improved durability of
Me-N-C catalysts is the next key practical challenge.<o:p></o:p></span></p>

<span style="font-family:"Arial Narrow","sans-serif"">This presentation will focus on novel understanding acquired on a recent set of Fe-N-C catalysts comprising, in parallel with atomically-dispersed Fe ions, a controlled amount of iron-based crystalline structures,
down to their complete absence. This set of catalysts has proven useful in advancing the understanding of the active site structure, role (or lack of) of Fe crystalline structures, and deactivation/degradation mechanisms [5-6]. Similarities and dissimilarities
between Fe- and Co-N-C catalysts will also be discussed on the basis of advanced
<i>ex situ</i> and recent <i>operando</i> spectroscopic characterizations. Remaining key challenges for the implementation of such catalysts in commercial fuel cells will finally be discussed.<o:p></o:p></span></p>
