System and process for generating electrical power

A process for generating electricity, comprising:

• in a first reaction zone, contacting a mixture of steam, a feed precursor, and an anode exhaust stream from a solid oxide fuel cell with a first catalyst at a temperature of at least 600° C. to produce a feed comprising one or more gaseous hydrocarbons and steam, where the feed precursor contains a vaporizable hydrocarbon that is liquid at 20° C. at atmospheric pressure and that is vaporizable at temperatures up to 400° C. at atmospheric pressure, and where the anode exhaust stream contains hydrogen and steam and has a temperature of at least 800° C.;
• in a second reaction zone, contacting the feed, and optionally additional steam, with a second catalyst at a temperature of at least 400° C. to produce a reformed product gas containing hydrogen and at least one carbon oxide;
• separating a hydrogen gas stream containing at least 0.6, or at least 0.7, or at least 0.8, or at least 0.9, or at least 0.95 mole fraction hydrogen from the reformed product gas;
• feeding the hydrogen gas stream to an anode of the solid oxide fuel cell;
• mixing the hydrogen gas stream with an oxidant at one or more anode electrodes in the anode of the solid oxide fuel cell to generate electricity at an electrical power density of at least 0.4 W/cm2;
• and
• separating the anode exhaust stream comprising hydrogen and water from the anode of the solid oxide fuel cell.
