How are cells stacked in a fuel cell stack?
A fuel cell stack consists of a multitude of single cells stacked up so that the cathode of one cell is electrically connected to the anode of the adjacent cell. In that way, exactly the same current passes through each of the cells.
What is the MPA of a dual fuel engine?
As discussed, a dual-fuel engine is usually a modified diesel engine. On a methane gas a rating of 1.3 MPa bmep can be achieved without risk of detonation. If the engine is to conform to BS 649 ratings the unit as a ‘dual-fuel engine’ will therefore have a ‘continuous’ rating of 1.2 MPa to allow for the 10% overload on dual-fuel for 1 hour.
What are the results of dual fuel engine?
The operation test results of the dual-fuel engine are explained. Two operation modes exist for the engine. In the diesel mode, it is compliant with the IMO NO x Tier II regulation and cleared the NO x regulation value by the combustion improvement.

What are the drawbacks of a fuel cell stack?
The low temperature, low pollution, and high power density of an RPEFC stack make it attractive. However, the high material cost is considered a major drawback facing worldwide RPEFC application.
How does a dual fuel HVAC system work?
During cooler seasons like fall and spring, the heat pump handles the heating duties. The dual-fuel system still incorporates the furnace, but without using any burners, just its air distribution features. The heat pump sends hot “refrigerant” through the air-conditioning coil within the furnace.
