Case study. The HydroGEN project – 3D printed sealing for solid oxide electrochemical cell stacks.
The HydroGEN project is a modular installation of reversible Solid Oxide Cells (rSOC), intended for integration into an industrial power plant to improve its flexibility of operation and increase the use of renewable energy sources in the hydrogen power sector. It is the brainchild of our partner, the Institute of Power Engineering (IEn).
Constructing the stack of solid oxide
electrochemical cells
HydroGEN is based on reversible solid oxide electrochemical cells operating alternately according to the power-to-gas (P2G) concept – in electrolyzer (SOE – Solid Oxide Electrolyser) and fuel cell (SOFC – Solid Oxide Fuel Cell) modes. The HydroGEN-based installation was designed and delivered by IEn in form of a container system integrated with EC Elbląg power plant within the Hydrogin project (realized by CBRF Energa Grupa Orlen and IMP PAN).
The sealing elements of the solid oxide cell stacks, manufactured by IEn, were made using a low-cost and waste-free 3D printing method on dedicated E-NIS machines designed and manufactured by Sygnis SA.
The role of seals in the stack
The seal used in order to separate the fuel and air zones inside the device is characterized by an ultra-low gas permeability coefficient. This requirement is met by glass-ceramic seals with strictly defined properties, optimized in the course of multivariate tests, which include: stability in oxidizing and reducing atmospheres over a wide range of partial pressures, resistance to thermal cycling over the life of the stack, compatibility of thermal expansion coefficient values with the parameters of other stack components, electrical insulation (preventing short-circuiting of cells in the stack), chemical compatibility with sealed components, as well as ease of manufacture and low cost.
The seals developed at the Institute of Power Engineering are made using an innovative method of 3D printing from glass paste using the E-NIS printers developed and manufactured by Sygnis SA. This is a low-cost and waste-free technology. The spatial printing technique allows the formation of a glass paste sealing material with appropriate rheological properties directly on the flat and corrugated surfaces of SOC stack elements. It also offers the possibility to build multilayer seals, thus allowing to optimize their thickness according to the application. Direct application of the seal to SOC stack components contributes to the elimination of redundant unit operations in the preparation of glass-ceramic seals and significant time savings, allowing the process to be more efficient and maintain its high repeatability.

3D printing allows for precise reproduction of the designed shape and ensures high quality and accuracy of the completed print. In addition, the use of waste-free 3D printing technology in the process of forming seals based on solid oxide electrochemical cells allows the production of seals with filler, patented by the Institute of Power Engineering. Such seals provide the required thickness and other gasket properties under equipment operating conditions, and are based on the use of, for example, waste ceramic powders from other industries as a sealing component.
