The paper describes an EasyTest cell developed for simple, safe and inexpensive to run testing and optimisation of the active materials (catalysts, catalytic supports, polymer membrane electrolytes) and electrode structures utilized in PEM Fuel cells and Electrolysers. The main advantages of the new EasyTest technique are demonstrated by a comparative study on the performance of two types of me...

Despite the significant improvement of polymer electrolyte membrane fuel cell catalyst activities, a cost-effective and stable membrane electrode assembly is still lacking, which greatly inhibits the commercialization of this efficient and environmental friendly technology in stationary and transportation applications. The main reason is that the engineering of different components of an electr...

We have achieved performance enhancement of polymer electrolyte membrane fuel cell (PEMFC) though crack generation on its electrodes. It is the first attempt to enhance the performance of PEMFC by using cracks which are generally considered as defects. The pre-defined, cracked electrode was generated by stretching a catalyst-coated Nafion membrane. With the strain-stress property of the membran...

A new Schiff base 2-aminothiophenol furfural self assembled monolayer (SAM) has been fabricated on a bare gold electrode as a novel sensor for determination of dopamine. Electrochemical impedance spectroscopywas utilized to investigate the properties of the Au 2-aminothiophenol furfural self assembled monolayermodified electrode (Au ATF SAM-ME) using the [Fe(CN)6]3-/4- redox couple. The electro...

Fe–N–C aerogel catalysts were prepared by sol–gel polycondensation of resorcinol, melamine and formaldehyde precursors in the presence FeCl3 salt, followed supercritical drying thermal treatments. The effect mass ratio on microstructure, iron speciation oxygen reduction reaction (ORR) performance aerogels was investigated N2 sorption, scanning electron microscopy, X-ray diffraction, photoelectr...

In this research, a PVC membrane electrode for Manganese (II) ions based on N-(2-Picolinamidoethyl)Picolinamide as neutral carrier was prepared. The electrode exhibits a Nemstian responseover Mn(II) concentration range of (1.0 x10-5 t01.0 X 10-1M) with a slope of 29.3±0.5 mV perdecade of concentration with a working pH range of 4.0-9.0. It has a fast response time (

Abstract Water management is a critical challenge in low temperature (LT) Proton Exchange Membrane Fuel Cells (PEM FC); condensed liquid appears mainly at the cathode side, where water from reduction reaction generated. Differences concentration may result transfer of to anode side across membrane electrode assembly (MEA). Excessive can negatively affect fuel cell performance, causing efficienc...

The use of Pt-based cathode catalyst materials hinders the widespread application anion exchange membrane fuel cells (AEMFCs). Herein, we present a non-precious metal (NPMC) material based on pyrolysed Fe and Co co-doped electrospun carbon nanofibres (CNFs). prepared are studied as oxygen reduction reaction (ORR) evolution (OER) catalysts in alkaline acidic environments. High activity towards O...

− The achievement of a proper and uniform pressure distribution between the membrane electrode assembly (MEA) and the bipolar plates of a proton exchange membrane fuel cell (PEMFC) is a key factor of stack design and assembly. Contact pressure levels are usually controlled by selecting an appropriate external clamping pressure on the endplates. Very few studies have been focused on the measurem...
