- Abstract
- The electrode's composition and structure, affecting ion-conduction and
water uptake and transport, is crucial for polymer electrolyte fuel
cells. This study investigates the role of particles versus dispersed
ionomer based on poly(arylene piperidinium) (PAP) for AEMFC. Mixed
ionomer electrodes, consisting of linear PAP ionomers and crosslinked
particles, are synthesized and evaluated in AEMFC single cells through
electrochemical characterizations. The addition of insoluble particles
corresponding to 5 % of total electrode weight leads to an increase in
peak power density of ∼60 % in comparison to when employing electrodes
based purely on the linear ionomers such as poly(terphenyl... (More) - The electrode's composition and structure, affecting ion-conduction and

and poly(terphenyl piperidinium-co-trifluoroacetophenone),
respectively. A deconvolution of cell resistance contributions based on
electrochemical impedance spectroscopy (EIS) data, combined with a
distribution of relaxation times analysis (DRT), shows a significant
decrease in effective cathode charge transfer resistance. This is
attributed to particles serving as bridges between the membrane and the
reaction sites, leading to increased ionic conductivity and active site
utilization via shortening the distance of water and ion transport
through the ionomer phase. In an expansion of the study, PAP particles
were added to an electrode sample based on commercial Aemion + ™. A
smaller peak power density increase of 27 % was observed, emphasizing
the importance of matching the chemical structures of the particles,
membrane, and linear ionomer. (Less)
