“…The drawback of titanium is its relatively poor corrosion resistance, especially on the anodic side where an oxide layer can form, increasing the resistance and lowering the performance of the stack over time. 8 Graphite, whilst having high conductivity, suffers from poor corrosion resistance, limited mechanical strength and high cost. 8 Various grades of stainless steel may be employed.…”

The electrolysis of water is considered a promising route to the production of hydrogen from renewable energy sources. Electrolysers based on proton exchange membranes (PEMs) have a number of advantages including high current density, high product gas purity and the ability to operate at high pressure. Despite these advantages the high cost of such devices is an impediment to their widespread deployment. A principal factor in this cost are the materials and machining of flow plates for distribution of the liquid reagents and gaseous products in the electrochemical cell. We demonstrate the production and operation of a PEM electrolyser constructed from silver coated 3D printed components fabricated from polypropylene. This approach allows construction of light weight, low cost electrolysers and the rapid prototyping of flow field design. Furthermore we provide data on the operation of this electrolyser wherein we show that performance is excellent for a first generation device in terms of overall efficiency, internal resistances and current-voltage response. This development opens the door to the fabrication of light weight and cheap electrolysers as well as related electrochemical devices such as flow batteries and fuel cells. Broader contextUptake of renewable energy generation, especially wind and solar power is increasing at a dramatic rate and has the potential to contribute greatly to mankind's management of climate change due to accumulation of CO 2 . Matching supply and demand of these intermittent renewable energy sources is challenging and solutions offered oen depend on the conversion of excess electrical power to chemical or potential energy for storage until required. Hydrogen is a potential storage medium in this regard and the use of polymer electrolyte membrane (PEM) electrolysers holds great promise for the generation of hydrogen from renewable sources. Successful realisation of this goal requires product development of all parts of the PEM electrolyser from the "active" components e.g. the catalysts, to the "passive" components, namely the structural parts of the electrolyser stack. 3D printing is an emerging technology which can be used in the fabrication of many different device types. Here we present the use of 3D printing to prepare components of an electrolyser cell and demonstrate its operation. This application of 3D printing enables rapid prototyping, cost reduction and a dramatic reduction in component weight. All of which may accelerate the development of new electrolyser technologies.

“…Though Pt is the most commonly preferred M ORR , it is very expensive and its usage is as high as 50-80% of total loading [7][8][9][10][11][12][13][14]. Hence, it is important to find alternative M ORR s that are less costly and provide acceptable performance.…”

This study aims to examine the influences of substrates/diffusion layers (DL) and oxygen reduction reaction catalysts (M , revealed that the roughness factor of the DL mainly determined the electrode performance for both water electrolyzer (WE) and fuel cell (FC) operations, while the contributions of porosity and substrate material were insignificant. When Pt-Ru was utilized as the M O R R instead of Pt, WE performance was enhanced and the electrode performance was assessed by analyzing round-trip efficiencies (ε . Improved efficiency was related to the additional catalytic action by Ru toward ORR during WE operation.

“…However, titanium tends to be passive in corrosive media, forming an oxide layer which leads to the increase in ICR and decrease in cell performance [17]. Jung et al [3,18] coated Au and Pt films on titanium as BPPs for URFCs, respectively. They found good performance in single cell experiments but did not report the electrochemical behaviors of the coated samples in detail.…”
