This steam reformer was combined with a polymer electrolyte membrane fuel cell (PEM FC) and a system test of the process chain was performed. The fuel processor comprises a prereformer step, a primary reformer, water gas shift reactors, a steam generator, internal heat exchangers in order to achieve an optimised heat integration and an external burner for heat supply as well as a preferential oxidation step (PROX) as CO purification. The fuel processor is designed to deliver a thermal hydrogen power output from 500 W to 2.5 kW. The PEM fuel cell stack provides about 1 kW electrical power. In the following paper experimental results of measurements of the single components PEM fuel cell and fuel processor as well as results of the coupling of both to form a process chain are presented.}, shorttitle = {Coupling of a 2.5 kW steam reformer with a 1 kWel PEM fuel cell}, endnotereftype = {Journal Article}, keywords = {imported } } @article{Ledjeff-Hey2000, title = {Portable PEFC generator with propane as fuel}, author = {K.

Propane as feedstack for hydrogen production offers a new way to a cheap fuel for fuel cells. The generation of a PEFC hydrogen fuel gas can be perfomed by catalytic cracking of propane. The decomposition of the liquified hydrocarbon takes place at temperatures above 800 degrees C at atmospheric pressure. A fuel processor based on this simple concept can be built much smaller and less expensive than existing ones using steam reforming technology. A propane cracking system works without shift-conversion, gas purification for removal of CO and without a steam generator. The removal of small amounts of CO from the hydrogen rich gas produced is possible by using a simple methanation step. A low cost portable fuel cell device is under development consisting of a polymer electrolyte fuel cell, a hydrogen production system based on catalytic cracking of propane; a propane storage container and an electronic control unit. Combined with a fuel cell providing 200 W gross electric power, a net power output of about 130 to 160 W can be achieved. The PEFC used will contain low cost bipolar plates made of carbon-polymer composite materials. (C) 2000 Elsevier Science S.A.
