Abstract
A hydrogen fuel cell water knockout device for an exhaust system of a heavy duty hybrid hydrogen fuel cell transit bus includes an expansion chamber housing forming an expansion chamber, the expansion chamber including a substantially vertical exhaust section and an exhaust flow path there through with a vertically lowest point in the exhaust flow path; a drain; and a condenser disposed at the vertically lowest point in exhaust flow path of the substantially vertical exhaust section in the expansion chamber so that the condenser condenses water from H2O exhaust without reintroduction of the water into the exhaust flow path and the water drains from the hydrogen fuel cell water knockout device through the drain.
Claims15
An exhaust system of a heavy duty hybrid-electric vehicle, the heavy duty hybrid-electric vehicle powered by a hydrogen fuel cell, the hydrogen fuel cell including a hydrogen fuel cell exhaust outlet that H2O exhaust from the hydrogen fuel cell is expelled from, the exhaust system comprising:
- an exhaust inlet coupled to the hydrogen fuel cell exhaust outlet, and configured to receive H2O exhaust from the hydrogen fuel cell;
- an exhaust outlet located vertically higher than the exhaust inlet, and configured to expel H2O exhaust from the heavy duty hybrid-electric vehicle;
- a water separation device mechanically coupled to the exhaust inlet and the exhaust outlet, and configured to separate water from H2O exhaust;
- and
- a drain coupled to the water separation device, and configured to provide a path for the separated water to leave the heavy duty hybrid-electric vehicle.
A hydrogen fuel cell water knockout device for an exhaust system of a heavy duty hybrid hydrogen fuel cell transit bus, the heavy duty hybrid hydrogen fuel cell transit bus including a hydrogen fuel cell supplying power in the heavy duty hybrid hydrogen fuel cell transit bus, comprising:
- an expansion chamber housing forming an expansion chamber, the expansion chamber including a substantially vertical exhaust section and an exhaust flow path there through with a vertically lowest point in the exhaust flow path;
- a drain;
- a condenser disposed at the vertically lowest point in exhaust flow path of the substantially vertical exhaust section in the expansion chamber so that the condenser condenses water from the H2O exhaust without reintroduction of the water into the exhaust flow path and the water drains from the hydrogen fuel cell water knockout device through the drain.
