Metallic bipolar plates for polymer exchange membrane (PEM) fuel cells are currently manufactured by stamping of thin sheets. However, there are dimensional and shape errors of microchannels because of forming limitation such as spring back of thin sheets after stamping. On the other hand,...

The present study deals with the production of biodiesel using waste fish oil. The research assesses the effect of the transesterification parameters on the biodiesel yield and its properties, including temperature (40–60 °C), molar ratio methanol to oil (3:1–9:1) and reaction time...

Fatty acid methyl esters prepared from canola, palm, soybean, and sunflower oils by homogenous base-catalyzed methanolysis were stored for 12 months at three constant temperatures (− 15, 22, and 40 °C) and properties such as oxidative stability, acid value, kinematic viscosity, low...

Using experimental study results, this paper aims at evaluating the different analytical models that are used for modeling Proton Exchange Membrane Fuel Cell Stack (PEMFC). Three static models such as those of Amphlett, Larminie–Dicks and Chamberlin–Kim are demonstrated. These models are...

This study investigated the feasibility of using lignin waste from pulp and paper industry as a mediator for treating ethanol stillage wastewater in microbial fuel cells (MFCs). Two configurations of MFCs used a salt-bridge and proton exchange membrane (PEM), and the influence of lignin and...
