Przedstawiono analizę stosowanych konstrukcji ogniw paliwowych SOFC zarówno o budowie płaskiej jak i tabularnej z punktu widzenia dynamiki pracy. Przestawiono główne parametry materiałowe (pojemności cieplne, przewodności cieplne), elektryczne (pojemności elektryczne, opory), przepływowe (składy gazów, prędkości przepływów, temperatury) jak i konstrukcyjne (pojemności akumulujące masę). Przedstawiono stałe czasowe wybranych procesów zachodzących w ogniwach oraz zaprezentowano koncepcję modelu dynamicznego ogniwa.

EN

The analysis of the construction of SOFC (both flat and tubular) according to dynamic operation is presented. The main material parameters (thermal capacity, thermal conductivity), electrical (electric capacity, resistance), flow (gas compositions, flow rates, temperatures) and structural (capacity accumulative weight) are set out. The time constants of selected processes in the cells and the concept of dynamic model of the cell are proposed.
