Santa Clara's two megawatt plant operated for 3,000 hours (125 days) and it rarely produced more than one megawatt of power before it fried itself. After 3 years of tinkering ERC has salvaged a 250 kilowatt unit (one eighth of the original operating power). Another American company M C Power demonstrated a 250 kilowatt unit in San Diego a year later in 1997 it only managed to produce 160 megawatt hours of power before being shut down for repairs.

Molten Carbonate Fuel Cells cannot operate until it's electrolyte becomes molten (liquid) at 1,200 degrees F. it's ion charge carrier is the carbonate. It's an impractical system when compared to the superior Seimens-Westinghouse's Tubular Solid Oxide Fuel Cells (large stationary power plants), or Global Thermoelectric's Planar Solid Oxide Fuel Cells (small stationary power plants). Neither Molten Carbonate Fuel Cells or Tubular Solid Oxide Fuel Cells are adaptable to mobile use like Global Thermoelectric's planar ceramic fuel cells are.
