In a paper in the Journal ChemSusChem they report that using a novel gel polymer electrolyte (GPE) enables stable performance close to the theoretical capacity (1675 mAh g -1 ) of a low cost sulfur-carbon composite with high active material loading, i.e. 70% S.

Comparison with conventional Cu/ZnO/Al2O3 catalysts revealed the same or better methanol synthesis activity, as well as considerably lower production of CO. In their paper, they suggested that this is a first step towards the development of small-scale low-pressure devices for CO 2 reduction to methanol. —Studt et al.

Cost reduction potential of a polymer fuel cell system using an ITM Power membrane. ITM Power has published figures showing what it believes is the highest ever polymer fuel cell power density using hydrogen as the fuel and ordinary air, rather than pure oxygen.

b) Comparison of cycling performance at C/2 with and without the PVP modification. Lithium sulfur batteries are of great interest due to their high specific energy and relatively low cost (e.g., To overcome this mechanism, they introduced amphiphilic polymers to modify the carbon surface.

Li-sulfur batteries—which conventionally use elemental sulfur (with conductive additives) as the cathode, an aprotic liquid electrolyte, and lithium metal as the anode—are under intensive investigation by research groups worldwide because of the promise for low-cost, high-energy storage.

million) to two UK fuel cell companies—ACAL Energy and ITM Power—to help deliver a step change reduction in the cost of the technology to about $35/kW. The Carbon Trust cost analysis applies to projected costs for the period 2030-2050, when fuel cell vehicles reach mass production quantities (500,000 units per year).
