In the period 1986-1990 research was carried out by the section Ceramic Research of the Netherlands Energy Research Foundation (ECN) within the framework of the IOP-TK project (Innovative Research Program-Technical Ceramics): ``Development of methods to manufacture porous ceramic products with specified porosity``. The motivation to carry out the project was aimed not only at ceramic membranes, but also at the development of fuel cell electrodes, catalyst supports and burner plates. A description is given of the project. An historical outline of the progress of the project is presented and attention is paid to the research and development strategy. Also an overview of the R&D carried out is given, as well as the most important results. Finally a list of ECN publications and a list of publications of general interest to the subject are presented. The three appendices hold detailed information on the project proposal, correspondence concerning the progress of the project, and copies of 7 articles published as results of the project. 22 figs., 3 tabs., 3 apps., 77 refs.
