Abstract

A diagnostic and heat management system for a fuel cell stack is provided herein that includes a diagnostic control analyzer that diagnoses and analyzes a state of the fuel cell stack by measuring a voltage and a current of the fuel cell stack. Also, an AC signal generator generates a diagnostic AC signal, and an AC component driving element that is included in an AC component in a current of the fuel cell stack. Additionally, a termoelement is driven as a heat absorbing device when a temperature of the AC component driving element is equal to or greater than a predetermined temperature and is driven as a heat emitting device when a temperature of the AC component driving element is less than a predetermined temperature, in order to manage heat generation in the AC component driving element.

Description

[0001] References to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2012-0155396 filed with the Korean Intellectual Property Office on December 27, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a diagnostic and thermal management system for a fuel cell stack that can diagnose a fuel cell stack and efficiently manage heat generated by the diagnostic process. Background technique [0004] A fuel cell is a device that converts chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols such as methanol are sometimes used. Fuel cells differ from batteries in that they require a constant source of fuel and oxygen to operate, but they can continuously generate electricity as long as these inputs a...
