Flow field designs for the bipolar plates of the proton exchange membrane fuel cell are reviewed; including the serpentine, parallel, interdigitated, mesh type or their mixtures, furthermore 2D circular and 3D tubular geometries, porous, fractal, and biomimetic flow fields. The advantages/disadvantages and tendencies from field optimizations are discussed. The performance of each flow field design is compared to the conventional serpentine flow field. Good flow field plates give uniform gas distributions, low pressure drop for transport, and sufficient rib area to provide high electronic conductivity. A good field should also prevent water condensation, remove water efficiently, and provide sufficiently high moisture content in the membrane. The demands on design are sometimes contradictory. Future work should aim for a flow field geometry and topology that produces uniform gas delivery at a low pressure-drop, and at the same time has an optimal channel shape for better water removal. It is concluded that for an area-filling gas distributor, the developments should aim to find a flow field in accordance with minimum entropy production, making an emphasis on multi-criteria optimization methods.

“…A 30 min purging using argon (Ar) gas was employed to de‐aerate the solution. For the PSP test, air was purged through the test solution for 30 min and a potential of 0.6 V was applied for a duration of about 24 h . The durability of the coatings (CrN, TiN, AlCrN, and AlTiN) was evaluated by measuring the current density as a function of time.…”

Proton exchange membrane fuel cells (PEMFC) attracted significant attention to meet energy demands for future applications. Graphite bipolar plates are currently being used due to its high corrosion resistance and electrical conductivity, but for economic reasons, metallic bipolar plates are being considered as a cost‐effective alternative. However, corrosion poses a serious challenge with the use of metallic bipolar plates. This study deals with the evaluation of the corrosion properties of TiN, CrN, AlTiN, and AlCrN coatings in PEMFC application. Electrochemical tests under anodic and cathodic conditions and interfacial contact resistance (ICR) test were used to investigate the electrochemical and electrical resistance properties. Results revealed that these coatings exhibit higher corrosion resistance as compared to 304 stainless steel in PEMFC environment. CrN and TiN coatings provided lower corrosion current density, higher durability, and lower ICR as compared to the ternary coatings. Corroded surface morphology revealed laths typed structure in the passive film of CrN and particle typed structure in that of TiN coating. However, AlCrN coating was found more durable than AlTiN coating under PEMFC environment. The incorporation of Al in TiN and CrN to form AlTiN and AlCrN coatings, respectively, affects the performance of the ternary coating in PEMFC environment despite the favorable influence it has on other properties of the coatings.

“…Bipolar plakalar (BP), yakıt pili sistemi içerisinde önemli bir bileşen olup, reaktant ve oksidant gazların sisteme dağıtılması, reaksiyonlar sonucu oluşan gazların sistemden uzaklaştırılması, elektronların sistemden çekilmesi, stağa mekanik destek sağlama gibi görevleri üstlenir [18][19]. Bipolar plakaların sahip olması gereken özellikleri; yüksek elektriksel iletkenlik, yüksek korozyon direnci, yüksek ısıl iletkenlik, düşük gaz geçirgenliği, yüksek mukavemet, düşük kontak direnci, hafiflik, düşük maliyettir [15,[20][21][22][23]. BP'ler stak maliyetinin yaklaşık %40'ını, stak ağırlığının ise yaklaşık %80'ini oluşturmaktadırlar [24].…”

AbstractOil reserves are not predicted to be wasted in the near future, but usage of hydrocarbon based fuels generates harmful emissions which affects the human health negatively. Therefore, there is a tendency towards renewable, alternative and clean energy sources worldwide. Fuel cells are electricity generators that can operate quietly and efficiently, and also without harmful emissions. Fuel cells can be used in aviation, automotive, military, submarine local and mobile applications which are also used in commercial applications. This situation show that comprehensive application fields of PEMFC. In this study, PEM fuel cell was selected as research area which is a type of fuel cell, and manufacturing techniques of bipolar plates investigated, which is a component of PEMFC. Traditional and innovator production techniques were researched and studies were evaluated in the literature considering the future perspective of the subject.
