FuelCell Energy Inc. said it will ship seven fuel cells to DaimlerChrysler's MTU Friedrichshafen unit, over the next 15 month for the use in the European tests of 250 kilowatt commercial fuel cell power plants. US security analysts were surprised by the size of the European order, and the news helped FuelCell shares bounce back after they dropped 13 per cent on Monday to a 15-month low after a setback to proposed $124 million deal in Connecticut.
