openGDE/bayadjamara: an open-source 3D-printable gas diffusion electrochemical reactor platform

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
