Carbon-polymer composite coatings for PEM fuel cell bipolar plates
(Journal article; Peer reviewed, 2014)A carbon-polymer composite coating on stainless steel 316L substrates was investigated for the use as bipolar plate material for polymer electrolyte membrane fuel cells. The coating consisted of 45 vol% graphite, 5 vol% ... -
Effect of anion exchange ionomer content on electrode performance in AEM water electrolysis
(Journal article; Peer reviewed, 2020)Anion exchange membrane water electrolysis (AEMWE) has acquired substantial consideration as a cost-effective hydrogen production technology. The anion ionomer content in the catalyst layers during hydrogen and oxygen ... -
Materials for Proton Exchange Membrane water electrolyzer bipolar plates
(Journal article; Peer reviewed, 2017)Titanium based BiPolar Plates (BPPs) are commonly used in Proton Exchange Membrane Water Electrolyzers (PEMWEs) today as they can withstand the harsh operating conditions experienced inside an operating PEM water electrolyzer. ... -
Measuring the thermal conductivity of membrane and porous transport layer in proton and anion exchange membrane water electrolyzers for temperature distribution modeling
(Journal article; Peer reviewed, 2019)Water electrolyzers that use a membrane electrolyte between the electrodes are a promising technology towards mass production of renewable hydrogen. High power setups produce a lot of heat which has to be transported through ... -
Soldering a gas diffusion layer to a stainless steel bipolar plate using metallic tin
(Journal article; Peer reviewed, 2018)A novel investigation to decrease the interfacial contact resistance of stainless steel bipolar plates was performed. A thin layer of Sn was electrodeposited onto a bipolar plate and subsequently joined with a gas diffusion ... -
The influence of graphitization on the thermal conductivity of catalyst layers and temperature gradients in proton exchange membrane fuel cells
(Journal article; Peer reviewed, 2018)As the proton exchange membrane fuel cell (PEMFC) has improved its performance and power density, the efficiency has remained unchanged. With around half the reaction enthalpy released as heat, thermal gradients grow. To ... -
Zirconium hydrogen phosphate as an additive in electrocatalytic layers for the oxygen evolution reaction in PEM water electrolysis
(Journal article, 2015)For reasons of electrode integrity and durability it is desirable to add zirconium hydrogen phosphate to electrocatalytic layers in PEM water electrolysis. Common synthesis methods are frequently associated with an ...
