Power module for motor vehicle, has control system controlling valve for supplying fuel cell by hydro carbonated fuel reformer or hydrogen storage tank based on external temperature and electrical power required by vehicle

摘要

The module has a fuel cell (16) supplied with hydrogen rich gas by a hydro carbonated fuel reformer (6). A hydrogen storage tank (1) has a pipe (2) supplying hydrogen to a three way hydrogen supply valve (3). A control system (11) controls the valve for supplying the fuel cell by the reformer or the tank according to external temperature and electrical power required by a vehicle. An independent claim is also included for a process of managing water circulating in a power module.
