Feasibility study of a double

Bipolar plate is considered as one of the main components of a fuel cell which has high weight and cost in the manufacturing of fuel cells. These plates are manufactured by different processes such as stamping, rubber pad forming, electromagnetic forming, and hydroforming, each of which has its own specific limitations. Among these processes, hydroforming is considered as a practical method in

A Review of Metallic Bipolar Plates for Proton Exchange

In this paper, we present the results of our studies on conceptual design and feasibility experiments towards development of a novel hybrid manufacturing process to fabricate fuel cell bipolar plates that consists of multi-array micro-channels on a large surface area. The premises of this hybrid micro-manufacturing process stem from the use of an internal pressure-assisted embossing process

Dana's New Bipolar Plate Delivers Durability and

In addition to composite bipolar plates, Dana designs and manufactures metallic bipolar plates, another critical component for enhancing the performance of fuel-cell powered vehicles. Manufactured with Dana's patented integrated sealing technology and in-line conductive coating, the company's ultra-thin metallic bipolar plates deliver superior power density, reliability, and durability.

A Hybrid Hydroforming and Mechanical Bonding Process

For a successful development of the proposed process, different scientific and research issues are investigated and discussed in this study. First, to characterize the material behavior of thin sheet metals at micro-scale, hydraulic bulge tests are performed to investigate the so-called "size effects" (i.e., grain, specimen, and feature size) on the material behavior.

Bipolar Plate Manufacture: Why Engineers Should

Photo chemical etching process offers manufacturers significant advantages when producing complex components such as bipolar fuel cell plates. Low-cost tooling First, and most importantly, photo etching requires no hard tooling, the use of digital tooling being inexpensive to produce and adapt, and therefore allowing designs to be optimised at minimal cost.

Fraunhofer: Flexible bipolar plates made of polymers

Bipolar batteries are designed to solve this problem by connecting the individual cells with each other using flat bipolar plates. However, this gives rise to other challenges: either the bipolar plates are made of metal and are thus prone to corrosion, or they are made of a carbon-polymer composite, in which case they have to be at least several millimeters thick as a result of the

Zr‐Based Thin Film Metallic Glass for Bipolar Plate in

Thin film metallic glasses (TFMGs), in this study, were coated on an austenitic stainless steel (AISI 316L) plate to enhance the corrosion properties of the metallic bipolar plate. A crystallized alloying target with the composition Zr 63.9 Al 10 Cu 26.1 and a grain size of less than 1 μm was prepared by consolidating the amorphous powder at 800 o C for 30 minutes.
