New fuel cell technology runs on solid carbon

Advancements in an exceedingly electric cell technology high-powered by solid carbon may build electricity generation from coal and biomass cleaner and additional economical, per a replacement article. Innovations within the anode, the solution and also the fuel permit the electric cell to utilize additional carbon, operate at lower temperatures and show higher most power densities than earlier direct carbon fuel cells (DCFCs).

Influence of Cathode Gas Diffusion Media Porosity on Open-Cathode Fuel Cells

We investigate the result of gas diffusion media (GDM) consistency on open-cathode cell operation in difficult close air conditions well-known to exacerbate either cell dehydration or liquid water saturation. A less porous cathode GDM improves cell contact that decreases surface contact resistances. we have a tendency to relate structural properties of the cathode GDM to heat rejection, gas transport, and water management within the open-cathode cell exploitation polarization behavior and chemistry electrical resistance spectrographic analysis.

Numerical and Experimental Investigations of Bipolar Membrane Fuel Cells: 3D Model Development and Effect of Gas Channel Width

Bipolar membrane fuel cells, that options a hybrid acid-alkaline membrane design, show nice potential for sensible applications thanks to their ability for self-humidification throughout operation. The principle of self-humidification behavior and associated transport mechanisms square measure reportable in previous studies with reduced-dimension models. This paper reports on a three-dimensional model and new experimental information that more elucidate the mechanism of self-humidification, give elaborate characterization of the results of style parameters on flow field and cell performance.

Long-term  effect of biochar amendment on the biodegradation of petroleum hydrocarbons in soil microbial fuel cells

Biochar is extensively applied in a change of contaminated soils. However, the impact of biochar on the biodegradation of fossil fuel hydrocarbons and electricity generation in soil microbic fuel cells (MFCs) remains unclear. Here, 3 biochars severally derived from poultry (chicken manure, CB), agriculture (wheat straw, SB) and biological science industries (wood, WB) were investigated after 223 days of the amendment. Consequently, high removal for alkanes was in CB with the mineral nutrition and phosphorus whereas aromatics were in SB with the foremost N content and therefore the highest molecular polarity. all-time low removal potency of total fossil fuel hydrocarbons was ascertained in Web with the very best expanse, whereas the foremost charge was obtained.

Cobalt-doped Titanium Dioxide Photochemical Fuel Cell for Wastewater Purification

In this work, an electrical phenomenon chemical science electric cell consisting of a cobalt-titanate (CoTiO3) anode and a noble metal (Pt) cathode was used for the decomposition of environmentally unsafe materials in waste matter. The CoTiO3 nanotubes (NTs) were ready through chemical science reaction of pure Ti (Ti) strips. The pigment (TiO2) nanotubes were doped with a metal salt via electrospinning followed by hardening to make CoTiO3. The addition of metal to the TiO2 NTs was tested to watch if chemistry chemical process properties hyperbolic in the presence of ultraviolet and visual light-weight. The will increase in chemistry chemical process properties were valid by comparison the measured potential variations (∆E) between the CoTiO3 check samples, and therefore the TiO2 management samples.
