IMPORTANT
There is no mention AT ALL in this article about automotive fuel cells. The type of fuel cell that is being developed for automotive uses is a PEM type fuel cell.
BUT THIS ARTICLE HAS NOTHING TO DO WITH PEM FUEL CELLS
The PEM fuel cell uses a membrane as an electrolyte. This membrane is highly sensitive to impurities - the impurities accumulate within the membrane and degrade its performance accordingly. PEM fuel cells CANNOT use reformed fuel because very minor amounts of sulfur and chloride will quickly degrade the cell.
The article is still important though - for PAFC type fuel cells. PAFC fuel cells have found good use as a power supply for large buildings (factories, apartment complexes, etc). These devices are about the size of a small one car garage. Such PAFC fuel cell units have built in reformers, and yes, CO removal is a significant part of the reformer.
This is good news for fuel cells, BUT IT HAS NOTHING TO DO WITH CARS
