Polimerowe ogniwa paliwowe Cz. I. Zasada dzia³ania, rodzaje oraz stosowane metody badañ

摘要: The paper is a literature review concerning polymer fuel cells. In the first part structure, principle of operation and types cells (FC) are discussed. In-situ techniques used for evaluation FC parameters in single cell or assembled stacks, such as current-voltage characteristics (polarization curve), current interruption method, cyclic linear sweep voltammetry, electrochemical impedance spectroscopy, cathode discharge mapping presented. mechanism functions components discussed details using example PEMFC (Polymer Electro- lyte Membrane Proton Exchange cells). Two distinguished, i.e. HT (High Temperature) LT (Low indicating advantages high-temperature opera-
