A Carbon Dioxide Tolerant Aqueous-Electrolyte-Free Anion-Exchange Membrane Alkaline Fuel Cell

A carbon dioxide tolerant aqueous-electrolyte-free anion-exchange membrane alkaline fuel cell.

Despite over a century of study and decades of intensive research, few fuel cell products have appeared on the market. The major inhibitor to mass commercialisation is cost. H2/air alkaline fuel cells (AFCs) containing KOH(aq) electrolyte promise the lowest cost devices, with the ability to use non-Pt catalysts. The fundamental problem with AFCs is that the KOH(aq) electrolyte reacts with CO2 (...

Poly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review

Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...

Ionic Copolymers for Alkaline Anion Exchange Membrane Fuel Cells (AAEMFCs)

A high-performance alkaline exchange membrane direct formate fuel cell

This paper reports on a single alkaline exchange membrane direct formate fuel cell (AEM DFFC) consisting of a carbon-supported palladium catalyst at the anode, a quaternized polysulfone membrane, and a non-precious Fe–Co catalyst at the cathode. It is demonstrated that the AEM DFFC yields a peak power density of 130 mW cm 2 with 5 M potassium formate (HCOOK) at 80 C. It is further shown that wi...
