Low Cost Bipolar Plates for Large Scale PEM Electrolyzers

Low-Cost and Durable Bipolar Plates for Proton Exchange Membrane Electrolyzers

Cost reduction and high efficiency are the mayor challenges for sustainable H2 production via proton exchange membrane (PEM) electrolysis. Titanium-based components such as bipolar plates (BPP) have the largest contribution to the capital cost. This work proposes the use of stainless steel BPPs coated with Nb and Ti by magnetron sputtering physical vapor deposition (PVD) and vacuum plasma spray...

Bipolar Plates

• good electrical conductivity (>100 S cm 1 bulk conductivity), • high thermal conductivity (>20 W cm ), • high chemical and corrosion resistance, • mechanical stability toward compression forces, • low permeability for hydrogen, • low-cost material being processable with mass production techniques, • low weight and volume, and • recyclable materials. Two different kinds of materials have been ...

Development of low-cost, high-efficiency PEM Fuel Cells

It is generally accepted that the global demand for energy will dramatically rise in the future. Fuel cells are promising as efficient, non-polluting power sources that produces little noise and have no moving parts. The main problem is the high cost of manufacturing the devices, which has largely limited them to a handful of exotic applications. The objective of the present project is the deve...

Low-Cost Test for Large Analog IC's

This paper outlines a basic block level test translation tool for analog systems. Test translation aims at minimizing DFT overhead in a hierarchical test translation scheme to meet the ever increasing integration, performance and test re-use requirements. The concept of analog signal propagation and necessary signal attributes are introduced to achieve e ective and accurate test translation. A ...
