Special Issue Information

Dear Colleagues,

As global warming becomes serious due to increased CO2 emissions from the combustion of fossil fuels, the demand for alternative energy resources is continuously growing. Fuel cells such as proton-exchange membrane fuel cells (PEMFCs) and anion-exchange membrane fuel cells (AEMFCs) using H2 as a fuel are one of the promising eco-friendly energy conversion devices since they produce electricity without pollution. Furthermore, strategies for the production and storage of H2 fuel have been extensively studied to accelerate the commercialization of fuel cell systems. In fuel cell applications, to decrease the use of expensive Pt or to replace the Pt-based catalysts by non-Pt- or carbon-based catalysts, scientist have proposed new ideas centered on the modification of catalyst structures. In the field of water electrolysis research, interesting approaches for the design of novel electrode and catalyst structures have been developed.

In this Special Issue, recent advances and novel ideas regarding the design of nanomaterials and electrode structures for fuel cell and water electrolysis systems are presented. This collection also covers the electrochemical analysis of nanomaterials for H2 oxidation/evolution, O2 reduction/evolution, and methanol oxidation reactions in electrochemical energy conversion systems.

This Special Issue is open to original research articles, as well as review papers, that help researchers worldwide understand the latest trend and progress in fuel cell and water electrolysis research.

Since trace amounts of CO in H2 gas produced by steam reforming of methane causes severe poisoning of Pt-based catalysts in polymer electrolyte membrane fuel cells (PEMFCs), research has been mainly devoted to exploring CO-tolerant catalysts. To test the electrochemical property of CO-tolerant catalysts, chronoamperometry is widely used under a CO/H2 mixture gas atmosphere as an essential method. However, in most cases of catalysts with high CO tolerance, the conventional chronoamperometry has difficulty in showing the apparent performance difference. In this study, we propose a facile and precise test protocol to evaluate the CO tolerance via a combination of short-term chronoamperometry and a hydrogen oxidation reaction (HOR) test. The degree of CO poisoning is systematically controlled by changing the CO adsorption time. The HOR polarization curve is then measured and compared with that measured without CO adsorption. When the electrochemical properties of PtRu alloy catalysts with different atomic ratios of Pt to Ru are investigated, contrary to conventional chronoamperometry, these catalysts exhibit significant differences in their CO tolerance at certain CO adsorption times. The present work will facilitate the development of catalysts with extremely high CO tolerance and provide insights into the improvement of electrochemical methods. Full article
