1. General performance and utilities/consumables consumption

1.1	General performance
	Description			Output	Purity			Pressure		Temperature	Dew Point
	Gas hydrogen			≥250Nm³/hr×4	≥99.999% H₂			1.6MPa G		30~40°C	≤-60°C
	Gas oxygen			≥125Nm³/hr×4	≥99.5% O₂			1.6MPa G		30~40°C	≤-60°C
	Note: 2.1.1The output flow Nm³ is volume under normal conditions (0°C, 0.1013 MPa A). 2.1.2 The performance is based on design basis of clause 1 in this technical annex. 2.1.3 The output flow of the hydrogen/oxygen is adjustable between 30~100% of total installed power.
