Design and experiment of fuel cell systems for marine application
Due to the new policies in the sector of marine transportation and strict emission regulations,fuel cells for marine application have received more and more attention,especially the proton exchange membrane fuel cell(PEMFC)system with high efficiency,low noise and modularity.This paper introduces the marine PEMFC system developed by Sunrise Power Co.,Ltd.,which is equipped with multiple safety parameter detection devices,adopts a targeted scheme for the selection of BOP components,and achieves the rated efficiency and peak efficiency of 45%and 62%respectively through water and heat management optimization and calibration.In order to prove the PEMFC system meeting the requirements of perfect function,safety and reliability,the performance evaluation test is studied and formulated by the methods of design tests,which are reliability test,cold start test and dual-machine parallel test.The test results show that after 200h dynamic working condition test,the performance of the system does not change at intermediate power,and the performance degradation rate of the stack is 1.2%at the rated power.Based on good water and heat management and multi-mode control methods,the purge time and cell voltage deviation are greatly reduced,and the cold start is successfully achieved when the ambient temperature is-30℃,which exceeds the most demanding requirements in the marine specification.Under the high-power demand and redundancy design goals,the double-PEMFCs makes the power output of the system assembly more stable and reliable.The system durability is improved through the alternate start strategy,and different working modes provide the basic conditions for system maintenance and trouble shooting.The PEMFC system has the ability to carry real ship applications.This paper provides a reference for the design and development of marine PEMFC systems.
