openGDE/bayadjamara: an open-source 3D-printable gas diffusion electrochemical reactor platform
Year: 2026
Type: article
Abstract: We introduce a flexible reactor platform for testing electrocatalysts, especially for gas-phase reactants or products. This open-source, 3D-printable platform has been designed for gaseous reagents in general and is readily modified to suit a range of applications, configurations and reactor sizes. We demonstrate the versatility of our platform with iridium(IV) oxide as a standard catalyst for water splitting, using a range of conditions that relate the system’s performance to the literature. To encourage adoption of our system, we have included detailed build instructions, 3D-printing tips, example reactor configurations and a guide on modifying the provided design code. It is our hope that the simplicity, low-cost and provision of design files will encourage use of the system to more easily enable appropriate testing of gas-diffusion electrocatalysts that will allow for ready cross-laboratory comparison and benchmarking.
