摘要

A 10-cells HT-PEFC stack with an active cell area of 200 cm~2 has been built up and tested regarding the temperature distribution from cell to cell and over the active area since not every cell is cooled. Measurements with artificial reformate as a fuel show that the vertical temperature distribution over the active area is sufficiently small, with a maximum of 5.1 K at 550 mA cm~(-2) . Also the temperature gradient from cell to cell is sufficiently small with 10.7 K at 550 mA cm~(-2). As a result it can be mentioned, that the heat pipe supported external cooling is well suited to cool HT-PEFC stacks with large active areas in reformate operation.
