Evaluation of low-cost cathode catalysts for high yield biohydrogen production in microbial electrolysis cell
As an ideal fuel due to the advantages of no pollution, high combustion heat and abundant sources, hydrogen gas can be produced from organic matter through the electrohydrogenesis process in microbial electrolysis cells. But in many MECs, platinum is often used as catalyst, which limits the practical applications of MECs. To reduce the cost of the MECs, Ni-based alloy cathodes were developed by ...
In-situ investigation of the cathode catalysts for PEM fuel cells using differential electrochemical mass spectrometry
Differential electrochemical mass spectrometry (DEMS) involves applying a potential across an electrochemical cell and measuring the resulting current while concurrently analyzing gas products with a mass spectrometer. We used DEMS to investigate the mechanism of carbon support corrosion (CSC) in-situ at the cathode of proton exchange membrane fuel cell (PEMFC). The cathode exhaust gases were ...
Continuous bioelectricity production and sustainable wastewater treatment in a microbial fuel cell constructed with non-catalyzed granular graphite electrodes and permeable membrane
Oxygen has been so far addressed as the most preferable terminal electron acceptor in the cathodes of microbial fuel cells (MFCs). However, to reduce the oxygen reduction overpotential at the cathode surface, eco-unfriendly and costly catalysts have been commonly employed. Here, we pursued the possibility of using a high surface area electrode to reduce the cathodic reaction overpotential rather ...
A comparative evaluation of palladium and platinum nanoparticles as catalysts in proton exchange membrane electrochemical cells
The goal of the present study is the development and comparative characterisation of carbon-supported and nanostructured Pd- and Pt-based electrocatalysts for hydrogen oxidation in Proton Exchange Membrane (PEM) H2/O2(air) fuel cells and proton reduction in PEM water electrolysers. Catalysts have been synthesised in a solution using a combined impregnation/reduction polyol method. They have been ...
Electrocatalyst Studies: Enabling Next-Gen Fuel Cells
What is a Fuel Cell? Fuel cells generate electricity through an electrochemical reaction rather than combustion. Inside a fuel cell, hydrogen and oxygen are combined to generate heat, water and electricity. They represent a clean, efficient, dependable, and quiet source of power that does not need to be recharged, but can continue to produce electricity as long as fuel is ...
