Final Report Summary

Bipolar plates, providing the structural integrity of a PEM fuel cell stack, are not an exception, as today's applied materials are currently still too costly to manufacture and less expensive alternatives lack the required corrosion stability and interfacial contact

[PDF] Low Cost Bipolar Plates for Large Scale PEM

PEM electrolysis is a promising technology for large scale storage of surplus electricity, though it is still costly mainly due to the manufacture of large area and high purity Ti bipolar plates (BPP). In this work we have developed an Au/Ti coating deposited by electrodeposition/thermal spraying on stainless steel BPP. The coating was physically characterized with SEM and electro-chemically

EUROPA

Metal based bipolar plates are very attractive, but a protective coating is needed to avoid corrosion and keep the interfacial contact resistance low. The STAMPEM-consortium was established acknowledging that further development of BPPs require Europe's best available resources, with respect to both human competence and infrastructure (laboratories).

Corrosion-resistant lightweight metallic bipolar plates for PEM fuel cells Hazem Tawfik IntroductionThe cost of fuel cell components and durability are important issues that need to be dealt with, especially when we compare the cost of electricity generated by PEM fuel cells with that generated by conventional power plants using fossil fuels.

Metal Bipolar Plate Coating

Therefore, metal materials cannot be used directly as bipolar plates. Metal bipolar plate coating material In view of the contradiction between the conductivity and corrosion resistance of metal materials, the current solution is mainly to modify the surface of the

Study of electrodeposited polypyrrole coatings for the

Polypyrrole coatings were prepared on stainless steel SS304 in order to study the corrosion protection provided by the conductive polymer in a simulated PEM fuel cell environment. The polypyrrole was deposited by electrochemical polymerization with 0.04, 0.07 and 0.14 g cm SUP-2/SUP onto SS304 electrodes. Polarization curves, taken after immersion for 1, 3 or 24 h in 0.1 M sulphuric acid

Final Report Summary

Corrosion, Contact Resistance, and Surface Characteristics

Second, corrosion and contact resistance tests for manufactured bipolar plates as well as blank stainless steel sheets were performed. Based on the corrosion test results, a faster stamping speed is found to be preferable for higher corrosion resistance and shorter production time.

Coated Stainless Steel Bipolar Plates for Proton Exchange

The stack comprises about 60% of the total cost of the PEM elec-trolyzer and the titanium bipolar plates (BPP) are responsible for half the cost of the stack.8 The BPPs are manufactured from titanium, which is highly stable to corrosion in oxidative 18,19

Corrosion Resistant, Lightweight, and Inexpensive

Corrosion resistant metal treated bipolar plates with higher rigidity and electrical conductivity than graphite were developed and tested for PEM fuel cell applications. Six replicas of single cells, three of which were made of graphite composites bipolar plates and the other three were made of the treated metallic plates.

Conducting polymer

Bipolar plate material should be corrosion resistant, conductive, gas impermeable, light weight (mobile applications) and economical. Graphite plates are used for bipolar plate applications but they are expensive, are brittle to make in thin plates with gas channels on sides, have high manufacturing cost and are gas permeable if too thin.
