The barriers in the widespread\nuse of fuel cells are their slow response for sudden load\nchanges and higher installation cost. In this paper a\nsimulation study of dynamic behavior of NexaTM 1.2kW\nPEM fuel cell with DC/DC boost converter is carried out for\ncompact design of PCU. The necessity for the requirement\nof boost converter compared with cascaded two stack fuel\ncell model is also addressed. Moreover the performance of\nthe simple DC/DC boost converter as power modulator for\nNexaTM 1.2kW PEM fuel cell model is analyzed for varying\nloads in order to control power flow for enhanced\nperformance.\";s:5:\"thumb\";s:100:\"images/t/3950/the-pem-fuel-cell-system-with-dc-dc-boost-converter-design-modeling-and-simulation.jpg\";s:6:\"thumb2\";s:101:\"images/t2/3950/the-pem-fuel-cell-system-with-dc-dc-boost-converter-design-modeling-and-simulation.jpg\";s:9:\"permalink\";s:82:\"the-pem-fuel-cell-system-with-dc-dc-boost-converter-design-modeling-and-simulation\";s:5:\"pages\";s:1:\"5\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:7;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"152054\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:8:\"elliebee\";s:9:\"author_id\";s:5:\"36204\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:28:\"The Recusal Volume 1 Issue 1\";s:11:\"description\";s:21:\"Parody.
