Title:
FUEL CELL CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2007/046192
Kind Code:
A1
Abstract:
A fuel cell control circuit (21) for controlling the output of a fuel cell (20) having
cells connected in series in multiple stages. The fuel cell control circuit (21)
has a detection section (22) for detecting the maximum voltage Vmax and
the minimum voltage Vmin of voltages of the cells, a comparison section
for comparing the maximum voltage Vmax and minimum voltage Vmin,
which are detected by the detection section (22), and first and second standard
voltages Vref1, Vref2, respectively, and a control section
(24) for controlling the output of the fuel cell (20) according to the result of
the comparison by the comparison section (23).
