Abstract
In this paper, a cooling channel was incorporated in the fuel cell to analyse the effect of cooling on fuel cell performance. Four different types of coolant combinations, namely DI100 (100% Deionised water), PG10 (90% DI water + 10% Propylene Glycol), PG20 (80% DI Water + 20% Propylene Glycol), and PG30 (70% DI Water + 30% Propylene Glycol) are used to analyse the fuel cell performance. A computational fluid dynamics model relying on a finite volume technique was used to assess efficiency. Performance evaluation was described as system temperature, operational parameters, coolant, and cooling channel geometry. The PEM fuel cell performance was good at PG30 combination, especially at high operating temperatures. The obtained results specify that the fuel cell performance was good at 356k. A decline in fuel cell performance was observed at temperatures between 362 and 371 k, obtained with the PG10 and PG20 conditions.
