An address element, including a polysilicon resistor functioning as a heating element and blocking diode preventing sneak current to unaddressed elements, is selectively addressed using row and column address lines in a thin film structure having a minimum number of address lines and a minimum number of layers. The resistor heater element is well suited for igniting a fuel cell such as a fuel cell in an array of fuel cells disposed in a thin film microthruster.
