Growth of Carbon Nanotubes on Graphene as Efficient Air–cathode for Highly H2O2 -producing Microbial Fuel Cell

Han S., Zhou C., Kansas State University, US

An efficient highly conductive three-dimensional (3D) air-cathode manufactured by growth of carbon nanotubes (CNT s) on graphene sheets (GNS) for the improvement of H2O2-producing microbial fuel cell (MFC) is reported. 3D architectured GNS-CNT s hybrid [...]

Electrophoretic deposition an emerging technology to support fuel cell nanoelectrocatalysts

Oropeza Guzmán M., Gochi-Ponce Y., Moreno G., Tecnologico Nacional de Mexico-Instituto Tecnologico de Tijuana, MX

A new challenge of nanoelectrocatalytic materials is to find a convenient method to support them on surfaces serving as fuel cell electrodes. Traditionally, researchers have tried to prepare colloidal inks containing the nanoelectrocatalyst previously synthesized [...]

Core-shell and Immobilized Nanoscale Ferrites for H2 Generation From Thermochemical Water-splitting

Amar V., Puszynski J., Shende R., South Dakota School of Mines and Technology, US

In this study, water was used as energy carrier for H2 generation via thermochemical water-splitting process using core-shell and immobilized nanoscale ferrite materials. Core-shell ferrite nanoparticles were synthesized using pluronic P123 templating assisted sol-gel method. [...]

A novel approach towards PGM-free PEM fuel cell cathodes

Anson C., Gerken J., Preger Y., Biswas S., Root T., Stahl S., University of Wisconsin-Madison, US

One of the major obstacles preventing widespread implementation of PEM fuel cells is the current requirement for prohibitive loadings of Pt at the cathode to achieve high activity for the oxygen reduction reaction. The Pt [...]

Improving Hybrid Efficiency and Flexibility by Integrating Thermal Energy Storage into the Fuel Cell System

Tucker D., Harun N.F., Zaccaria V., Shadle L., National Energy Technology Laboratory, US

Power plants must be flexible in operation to meet changing load requirements throughout the day while ensuring economic feasibility. As renewable energy systems penetrate the market producing inconsistent power, the primary concern of power plants [...]

The maximization of hydrogen rhythmic production in large scale photobioreactors from genetically modified microalgae biomass

Dias F.G., Vargas J.V.C., Kava V., Ordonez J.C., Balmant W., Mariano A.B., Federal University of Parana, BR

A transient mathematical model for managing microalgae derived hydrogen production as a source of renewable energy is developed for large scale compact photobioreactors (PBR). The model allows for the determination of microalgae and hydrogen mass [...]

Lower-cost Hydrogen (H2) Fuel Production from Distributed Wind via Paralleled Self-Excited Induction Generators (SEIG’s) & Close-coupled Electrolysis at Multi-turbine Off-grid Windplants

Leighty W.C., Alaska Applied Sciences, Inc., US

We may significantly reduce the cost of wind-source hydrogen fuel generation by simplifying the design, capex, and O&M costs of wind turbines, windplants, and electrolysis plants, by: 1. Designing the turbines with simple, robust, low-cost, [...]

Zn(Ⅱ)-Based Metal-Organic Framework/Nafion® Composite Membrane with High Proton Conductivity for Fuel Cell Applications

Kim H.-J., Kabir L., Kyungpook National University, Daegu 41566, Korea, KR

Metal-organic frameworks (MOFs) can serve as a scaffold to anchor acidic groups and provide efficient proton transfer pathways owing to their highly ordered structures and modular nature. Intentional coordination of MOFs with a conductive polymer [...]
