PEM fuel cells are very promising for portable applications. A key component of fuel cell is the flow field plate through which hydrogen will reach the anode, oxygen will reach the cathode and electron collection. Flow field plate made of silicon is not a good electrical conductor , so electrical contacts has to be attached to the Gas Diffusion Layer (GDL) for taking the power to outside ...

Dosing a predetermined quantity of one liquid into another, in a controlled fashion, is a process often encountered in a variety of operations at both industrial and laboratory scales. This process becomes a challenging one if it has to be carried out in a continuous mode, without using any dosing pump and if the dosage levels are very small. A possible simple and elegant solution to the problem ...

Thermo Mechanical Analysis of Divertor Test Mock-up using COMSOL Multiphysics

Y. Patil[1], D. Krishnan[1], S. S. Khirwadkar[1]
[1]Institute for plasma research, Bhat, Gandhinagar, Gujarat, India

Divertor is act as an exhaust for the nuclear fusion reactor. Main function of a divertor is to remove the heat flux from the plasma. Plasma facing components of the divertor are made up of Carbon (Graphite/CFC) and tungsten like materials[1]. Hence these materials are exposed to the transient heat loads up to 10MW/m^2. Thermo mechanical behavior of Graphite test mock-up under the transient heat ...
