Reformer for electric vehicle fuel cells, passes heating flow through second reformer countercurrent to hydrocarbon-containing flow

摘要

In one phase of operation, the heating flow (6) passes through the second reformer (3) countercurrent to the hydrocarbon-containing flow (4). In one phase of operation, the heating flow passes entirely countercurrent to the hydrocarbons (4) through both the first and second reformers (2, 3). The heating flow (6) is passed through a second heater (9), to heat both reformers (2, 3) during start-up. In a variant, the heater is located between the reformers. Inlet and/or outlet (12, 11) of the first and/or second heater include controlled dosing equipment for the heating flow (6). The reformers and heaters are coaxial. The heating unit (5) is central with respect to the reformers and heaters (8, 9). The corresponding installation and vehicle including it, are also claimed.
