Based on the cell current and voltage the energy balance can be calculated.
In the following the electric cell output power (often referred to as "DC power")
and lower heating value (LHV) are calculated. The numbers here are per cell area for
being cell and stack size independent. The quotient of both is often referred to as
LHV based DC efficiency.
```python
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
efficiency = dc_power / lhv # LHV based DC efficiency
print(f"DC power: {dc_power:.2f} W/cm²")
print(f"LHV based DC efficiency: {efficiency*100:.1f} %")
