Abstract
Official abstract text for this publication.
Fuel cell system mounting fuel cell vehicle including: fuel cells having platinum-containing catalyst as electrode catalyst; cell voltage meter configured to measure cell voltage of fuel cells; and controller controlling fuel cell system, wherein (a) cell voltage meter obtains first cell voltage in predefined idling state of fuel cells, (b) in response to changing operation state of fuel cell vehicle from driving state to stop state, controller changes operation state of fuel cells to idling state, and cell voltage meter obtains second cell voltage of fuel cells in idling state, (c) controller uses difference between first and second cell voltages to obtain recovery process voltage for recovering catalyst of fuel cells and recovery process time duration wherein cell voltage of fuel cells is kept at recovery process voltage, and (d) controller reduces voltage of fuel cells to recovery process voltage for recovery process time duration, preforming recovery process of catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control method of a fuel cell system to be mounted on a fuel cell vehicle and includes fuel cells having a platinum-containing catalyst as an electrode catalyst, the control method comprising the steps of: (a) obtaining a first cell voltage of the fuel cells in a predefined idling state state; (b) in response to a change in operation state of the fuel cell vehicle from a driving state to a stop state, changing an operation state of the fuel cell ve…
