Abstract
Official abstract text for this publication.
The progress of activation of a fuel cell is appropriately transmitted in accordance with the rise of the temperature of the fuel cell, and an estimated time till the completion of the activation is displayed with higher accuracy. To realize this, the current percentage of a fuel cell temperature is displayed on a gauge (G) which displays, as a starting point, the temperature of the fuel cell at the start of the activation and which displays, as an end point, the temperature of the fuel cell at the completion of the activation. The percentage of the temperature is displayed as the estimated time till the completion of the activation, whereby an adverse effect due to a low accuracy in the case of the estimation of the time is eliminated. When the fuel cell is activated for a failure check, the percentage of an actually elapsed time with respect to a time required to complete the failure check may be displayed on the gauge (G). After comparing the percentage of the actually elapsed time with respect to the time required to complete the failure check with the percentage of the temperature of the fuel cell, the smaller value is preferably displayed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel cell system comprising a fuel cell which generates a power by the electrochemical reaction of a fuel gas and an oxidizing gas, the fuel cell system further comprising: a control unit programmed to calculate a ratio of a difference between a current fuel cell temperature and a fuel cell temperature at a start of activation against a difference between a fuel cell temperature at a completion of activation and the fuel cell temperature at the sta…
