1) A system combining a solid-oxide fuel cell with a gas turbine has been proven to achieve higher operating efficiencies at high pressures. The exhaust gases from the fuel cell enter a steam turbine as shown in Figure 1. Determine the shaft work done by the turbine. SOLID-OXIDE FUEL CELL P₁ = 1.0 MPa T₁ = 800 K (₁) H20 = 105 mol/s u₁ = 50 m/s Q = -1.16 x 10¹ J/kg Figure 1 W₂ = ? P₁ = 0.1 MPa T₁ = 400 K (₁) H20 = 105 mol/s U₁ = 80 m/s 1) A system combining a solid-oxide fuel cell with a gas turbine has been proven to achieve higher operating efficiencies at high pressures.
