Critical advancements in achieving high power and stable

Despite great progress in the development of nonprecious metal catalysts (NPMCs) over the past several decades, the performance and stability of these promising catalysts have not yet achieved commercial readiness for proton exchange membrane fuel cells (PEMFCs). Through rational design of the cathode catalyst layer (CCL), we demonstrate the highest reported performance for an NPMC

A review of the stability and durability of non

A major hurdle to the widespread commercialization of proton exchange membrane fuel cells (PEMFCs) is the high loading of noble metal (Pt/Pt-alloy) catalyst at the cathode, which is necessary to facilitate the inherently sluggish oxygen reduction reaction (ORR). To eliminate the use of Pt/Pt-alloy catalysts at the cathode of PEMFCs and thus significantly reduce the cost, extensive research on

Reviving the lithium

In the past several decades, the research communities have witnessed the explosive development of lithium-ion batteries, largely based on the diverse landmark cathode materials, among which the application of manganese has been intensively considered due to the economic rationale and impressive properties. Lithium-manganese-based layered oxides (LMLOs) are one of the most promising cathode

2013/10/14An alternative approach is to replace Pt with abundant, nonprecious materials that are not susceptible to price in?ation under high-demand circumstances. The class of non-precious cathode catalysts that has attracted the most attention over the years is pyrolized metal porphyrins, with cobalt and iron porphyrins viewed as the most promising precursors.

Ballard to Offer World's First PEM Fuel Cell Product Using

2017/9/12Nisshinbo's Non Precious Metal Catalyst is based on a carbon alloy material which further reduces the cost of an air-cooled fuel cell stack. Ballard and Nisshinbo jointly presented a paper entitled "Non-Precious Metal Catalysts: Cathode Catalyst Layer Design Considerations for High Performance and Stability" at the SSI-21 Conference held in Padua, Italy in June 2017.

Electrode materials for microbial fuel cells: nanomaterial

2015/11/5The higher cost of metal catalyst along with limited global reserve appealed researchers to find an alternative with comparable catalytic activity, less expensive materials for ORR at cathode. Recently, it was reported that metals as catalyst in ORR only promote the formation of active sites and have no role in catalytic function [ 77 ].
