Fuel cells

A fuel cell is a device that generates electric energy through electrochemical reactions between an oxidizing agent and a fuel – a material that stores energy in chemical form. Both species are not stored in the fuel cell but must be supplied from external sources.

    Understanding the nature of active sites in carbon electrocatalysis remains a subject of dispute and a great scientific challenge. Convincing new evidence supports the fact that, for oxygen reduction, defects present in carbon materials are more powerful catalytic sites than nitrogenated sites.

    Scalable interconversion between chemical and electrical energy requires compact, selective and highly efficient reversible electrochemical cells. Now, protonic electrochemical cells with tailored catalysts and ceramic architecture are shown to operate reversibly with high performance and to be integrable with catalytic CO2 conversion.

    Direct liquid fuel cells are usually impeded by the cross-over of their reactants, which depreciates their performances. An asymmetric bipolar membrane is now shown to effectively separate the anolyte and catholyte of a direct borohydride hydrogen peroxide fuel cell, enabling high power and promising durability.
