Development of the cooling and formed water distribution measuring technology in the metal separation plate by the neutron visualization technology

- Project Introduction
In general method, the measurement of the water in real-time is impossible, because the part of the fuel cell is invisible. So, the neutron visualization technology, the appropriate method to measure the water in the invisible fuel cell which is consisted with metal components. In this study, water distribution in a fuel cell that adopts metal separation plate is visualized using Neutron Radiography. From this analysis, optimal design will be developed.

Research on fuel cell performance enhancement

- Project Introduction
The distribution and transfer phenomena of water are affected by the form and surface characteristic of the MEA (Membrane Electrolyte Assembly) and GDL (Gas Diffusion Layer) in the fuel cell. In this study, the understanding of the heat and mass transfer in the porous media in the fuel cell will be achieved. For this aim, POSTECH (TPFL), University of Michigan (Prof. Kaviany), and University of Cincinnati (Prof. Son) are collaborating.

SMART project

- Introduction

The System-integrated Modular Advanced ReacTor (SMART) is a small modular integral-type pressurized water reactor that is developed for the dual purposes of seawater desalination and small-scaled power generation.
The heat transfer characteristics of steam generator and PRHRS condensation heat exchanger are the key parts of SMART's overall performances and safety. Thus It is required to do experiments on verification and development of analytical ways of the project's heat transfer performances and safety.
