【発明の名称】燃料電池の制御装置
Document Type and Number:
Japanese Patent JP2918759
Kind Code:
B2
Abstract:
PURPOSE:To properly and automatically control each current of a plurality of fuel cell stacks which are connected in parallel while even variation with time is being taken into consideration, and thereby enhance reliability. CONSTITUTION:A controller C compares the detected output current of fuel cell stacks S1 through Sn connected in parallel, with target values separately set by each so as to control gas feed valves IA and IB for the respective stacks, so that each gas pressure within the respective fuel cells is thereby optimized. The controller also controls the concentration, temperature and the like of oxidizing gas A and fuel gas B. Moreover, as the aforesaid target value, the two kinds of values are set, the aforesaid control is usually executed based on the first target value, and when fuel cell performance is deteriorated, execution is shifted to control based on the second target value.
