```python ```python
dc_power = cell_voltage * terminal_current # W/cm² dc_power = cell_voltage * terminal_current # W/cm²
lhv = gp.fluid({'CH4': 1, 'H2O': -2, 'CO2': -1}).get_H(25 + 273.15) # LHV of methane

# LHV based chemical input power:
lhv_power = lhv * terminal_current / (2 * z_O2 * F) # W/cm² (two O2 per CH4 for full oxidation)
efficiency = dc_power / lhv_power
