Is gold used like platinum in automotive catalytic convertors, for controlling exhaust emissions or in fuel cells?

Current catalysts are not very efficient until they have warmed up. In addition, a number of companies have patented technologies based on the use of gold for cleaning impuririty gases from hydrogen used to power fuel cells. Impurities like carbon monoxide reduce the efficiency of the fuel cell and it maybe that the use of gold in this application helps fuel cells to become more efficient and commercially viable.
